It can run ecc unbuffered if paired with a xeon processor. just not ecc registered.
Maybe it can run ecc unbuffered with an i7 cpu. But I've never tried this.

Btw. I too ran into xeon processor support probs on an x58 board (lanparty jr x58). At least your board boot it up. Mine never supported 6 core xeons. Would not boot up

Anyhow the lanparty jr x58 worked fine with a xeon w3520 / E5520 and ecc unbuffered ram.

Sold that x5670 yet? :)

Because i really have so little experience using ecc ram can you post a link to ebay or wherever people are selling this ram (3 x 8gb sticks) your thinking of using....Your not the first person to ask about this and if it ends up working for you other people might want to know. Also i was just curious how the price compared versus normal buffered ram

I never shopped for 8gb of ecc unbuffered. only 4gb.

buffered ram only works on dual workstation/server class. (registered ram)

for the 4gb module we're talking a $5 difference. a single 4gb reg ram dimm is about $15. where as the ecc unbuffered 4gb dimm goes for $25. And usually you only see lots of 4 (not 3) for reg ram as populating cpu ram banks unevenly results in the total ram not being recognized.
When I shopped for ram a few months ago I saw a lot lots of 4 closing at $60, or being sold BIN at $60. With unbuffered ram that goes up as much as $100.
I don't know where you're going with this. But I wouldn't switch to a workstation class machine. You're gonna be disappointed.
 
Thanks for all of the replies. Sorry I've been MIA for a few days, but life keeps me busy sometimes with the swing shifts. I'm definitely interested in doing this now. Nothing like breathing a little life in and older machine.

Did that chip already sell? Didn't see in in FS/FT.

I looked up 8gb ecc unbuffered dimms. If anything they're even costlier than desktop ram (non-ecc, unbuffered). And you never see them post in bid auction. Just BIN.
The 4gb unbuffered ecc on the other hand seem more available and cheaper.

Now, here's how you can discern between the various types of ddr3 ram.
yuo have this one in this auction for example. PC3-12800U If you look at the dimm stick, it has 4 chips on both sides. And the U at the end denotes "unbuffered". The PC3-10600E, or PC3-12800E Stick looks almost exactly the same. Except that it has an uneven amount of chips on either side.
The registered ram on the other hand (PC3-10600R) has a chip right smack in the middle of the dimm which is a memory controller chip. And it usually is bigger than the other chips.
So to recap:
PC3-10600U = non-ecc, unbuffered. missing controller chip. even amount of chips
PC3-10600E = ecc, unbuffered. missing controller chip. uneven amount of chips
PC3-10600R = ecc, registered. has a controller chip in the middle (usually a bigger chip)

Addendum: you can't mix reg ecc with either ecc unbuffred, or non-ecc ram. And you probably can't mix unbuffered non-ecc with ecc unbuffered. ( I should've tried this before selling my lanparty jr )

Addendum #2: pc3-10600u and pc3-10600e may work after all. I just checked my nephew's thinkstation s20 and it has both 2x1gb pc3-10600e and 2x2gb pc3-10600u installed in his system. If anyone ventures to test this out. 2gb unbuffered ecc ram can be had for $10 a pop

And again, avoid registered ram. It only is compatible with dual cpu workstation and registered ram itself (can't be mixed with any other ddr3 type)

It can but the boards are finicky about what ram they will accept. About 50% of the ecc ram ive tried has worked and the same ones worked in x58 and x79 boards with xeon cpus.
 
I have only used ES xeon cpus in x79, and all of the motherboards (several different asus, gigabyte, and asrock ones) I tried them with worked in although they can be finicky with bios versions etc.

I have not tried retail xeon cpus in the boards because they just cost too much and don't offer anything over the x58 xeons except for a major dent in your wallet and no oc capability.

I see. I guess we're left to do the guesswork by trial and error. Just matching by socket type isn't good enough. Most of the time board manufacturers don't even document what processors are supported. My guess is that intel hands them the micro codes and they just push them with the latest bios updates without knowing what processors are supported.
 
yea its not a surprise that intel doesn't want the cpus to show up as "officially supported"

If you look at the x58 chipset on the intel ark it only shows that it supports the i7's and a few xeons on there too, just the W ones (no X, L or E)
 
I don't think it's an Intel problem. Several EVGA boards needed a mod to support Xeons and I don't think we can blame that on Intel.

Really just asking questions, cause thats how we start to learn. I didn't know any of that stuff you were talking about so i guess you could say memory was not my strongest point.
The picture im starting to get is there 2 main types of ddr3 memory: ecc (server) and non ecc (Desktop) and of course there is a buffered/Registered version of each type which now makes 4 basic types not counting speed or timings. Now the type of ram I have is 2gb ddr3 patriot viper
20-220-365-07.jpg

Which i assume is Non ECC Registered PC3 12800...I guess places like newegg just break it down into server (ecc) memory and desktop (non-ecc) memory where mine is just classified as desktop....I probably got it wrong still huh? Anyway lol Im seeing ddr3 1600 non ecc ram for about 100 bucks for 12gigs ...and the ecc is cheaper right? on ebay i guess?
See now i see they have ecc in desktop and server ram so i still have it wrong:D....How does newegg for example decide what is server and what is desktop?

Your RAM is not registered, it's unbuffered. The vast majority of RAM you'll come across is unbuffered, non-ECC. Error-correcting code memory is much more reliable, one of the reasons they're used in servers where correct data is vitally important. I'm not saying I'm an expert on the subject, but I've done my fair share of reading up on it. For the average consumer, there's no need for ECC or buffered memory.
 
As far as the bios on that Asus P6T D V2 you will need the newest bios.
Mine would not post at all with out it. I didn't have a CPU to flash with so I bought a bios chip off ebay 13$ or so.
I suppose I could hot flash my old bios and sell it, or save it as a spare.

There's no such thing as registered unbuffered, or registered non-ECC. Registered ram can only be ECC. But ram can also be ECC and unbuffered.

There are only three types.
  1. The so called desktop ram. DDR3 Non-ECC Unbuffered ( PC3-8500U / PC3-10600U / PC3-12800U ) or UDIMM
  2. The Workstation/Server Ram with only ECC. DDR3 ECC Unbuffered ( PC3-8500E / PC3-10600E / PC3-12800E )
  3. And the Workstation/Server Ram with both ECC and Registered support. DDR3 ECC Registered ( PC3-8500R / PC3-10600R / PC3-12800R ) "Buffered"

The other variation are the PC3L type. (Low voltage ram for servers). Which are about half the height of regular dimms. You don't see those on desktops.
Patriot, Gskills all those companies that simply rebadge hynix/elpida/samsung ram, do not sell server memory afaik. The ridiculous sized heatsink on the ram pictured in your post gives it away as desktop ram. There's no need for registered ram to be overclocked. There isn't even that feature on most server boards. So large heatsinks are useless on server (registered) ram.

Xeon CPUs support ECC ram. So they should be able to use ECC Unbuffered ram. However, whether or not the motherboard enables that features is something I don't know, or care. There's the likelyhood a gaming motherboard would not use the ECC feature. as long as the ram works, you shouldn't care either. In other words is a feature that won't prevent the ram from working.

Use just 1 or 2. Avoid any ram that ends with (R)

If you mix speeds it will default to the lowest speeds across all ram. If you mix 1 & 2. The ECC feature will be disabled.

Next step would be for someone to confirm whether ECC unbuffered can work with processors that don't support ECC like the i7-920. My guess is it doesn't
 
Hi all,

Would be great to receive some advice. I presently have an i7 920 overclocked to 3.8Ghz on a Gigabyte EX58-UD5 rev1 mobo and Corsair 6GB DDR3 PC3-12800C8 1600MHz Ram. I’ve read about 15 pages from the start of this thread and the last 5, dating from this time last year to the present day.

Is upgrading to the Xeon still a good option?
Which Xeon chip is the best one to go for? The options I am considering are 5650 or 5670 or 5690

I’ve noticed a number of models available on eBay and don’t really know which chip would be best for the highest 24/7 overclock.

Thanks in advance for any feedback - I was one of the first to jump on the 920 D0 bandwagon following a chat with a guy in switzerland and russia and subsequently posted here about it. The mayhem that swiftly followed was a marvel to watch. That said - I’m one of the last to get on the Xeon bandwagon - it’s been so long since I’ve been on the PC scene that I can’t even remember my previous login! Cheers.

YES! An Xeon is still a great upgrade option. Which chip you should get depends on how high of a multi you want to play around with. I would go with the cheapest chip possible, either a x5650 or x5660. Higher multi usually does not mean a higher overclock with these chips.

5670 is at the sweet spot price wise and im not positive the 5690 will give higher clocks but its possible and usually twice the price

Well i have yet to hear of a direct comparison between those 2 but i think its unlikely....If you already own an x58 system (as a second pc) and just had to drop a xeon in it...i would do it regardless. Don't go and buy a bunch of x58 stuff to replace a 2500k. People can generally get most of there money back on the chip depending on what you pay, but as a general rule of thumb its usually only a recommendation to purchase the xeon if its the only part to buy

Here's another way of looking at it: What is your cpu usage while playing? Post a few screenshots with msi afterburner running showing gpu and all cpu cores usage and it would help make a better guess. If all 4 cores are at 100% usage then it might help, but the issue is most games up till now only use 2-4 cores. This will change with direct x12 but thats a long ways off

Hi,

To answer your question I would say no. You would probably be better off working on overclocking your 2500k higher as 4 ghz is a fairly mild OC for that cpu. Maybe if you were doing SLI or something it might make a difference but from the becnhmarks below it looks like GTA V doesn't do much with more than 4 cores. The 2500k at stock is roughly equal to the FX-8350 and FX-9590 (which both start with a much higher base clock and have 4 more cores than 2500k)

Hey fellas,
I've been reading through this thread for the last two months or so. ( I read slow ;) )

Replaced my i7 920 C0 with an Xeon 5675 B1 a couple of days ago.
Bumped the clock up to 3,7 GHz ( definitely going higher ) which was my highest stable oc on the 920, and the xeon did it with the initial 1.2 V i set it to, where as my old cpu needed a hefty 1.39 V.

So that was pleasant.

Anyway, onto my question,
I noticed that the Xeon kicked down one multiplier from time to time when i stressed it with IBT.
There was a bit of discussion about the P6T's TDP throttling around pages 41 and 54

So people with P6T's, have you crossflashed?
How essential are the performance gains made possible from the increased TDP ceiling, if any?

I presently have a triple channel kit (RAM): Corsair 6GB DDR3 PC3-12800C8 1600MHz Ram.

Reading the specs of others here - I presume 6GB RAM doesn't cut it these days.. what is considered sufficient for gaming and light desktop work? I presume that I can't mix and match ram sticks. What would you guys suggest?

My wife's rig has been running fine with mixed RAM kits for more than 5 years now. Half Corsair and half G Skills.
 
12gb seems to work real well with everything I do. I have used 6 x 2gb or 3 x 4gb and been happy with it.
Ihave been using different sets mixed, but they are the same make and model, just different speed and timings.
Gskil 777-21 with gskill 787 21 or 888 24 ripjaws series. Or two Sniper 1866 with one 1600
Also Kingston 1333 and 1600 Blu-Red series and they work well at 1600mhz 999 25.
I just set the timings and speed manually and so far so good.
Not tried Kingston with Gskill,. I just try to use sets that are close to each other.

Doubt it. It wouldn't be worth going through all that trouble to switch to an older CPU. Getting that 2500k to 4.5ghz+ would make more sense.

I haven't yet. I run at 200bclk so I'm really only interested in P6X58D Premium crossflashing for offset voltage.

Well your multiple for a Xeon 5675 B1 even without turbo should be 22 or higher even without cross flashing. This would give you around 4.2ghz right off the get go at a blck of 191 at least right? Now for some reason you cant get 191 blck stable then cross flashing might be needed. My board loosed the use of one pci slot after cross flashing so i went back to stock bios. If i wasn't using that particular slot i might have kept it that way, but it also seemed to require about the same voltage anyway, so for mine it wasn't a huge gain with the turbo multi.

Well i can say for the most part 6 gigs would be ok, but i do go over that from time to time if i don't reboot for a few weeks. I think the caching software with Samsung magician also use up a fair amount of ram as well, so folks not using software like this wont use as much ram either. If i only had 6 gigs, i guess i probably buy 6 more since its 50-100 bucks at most right? But it wouldn't be a high priority either;)

Yes it will. You gain more cores, and you gain a higher cache. These 2 things alone will give you a bump in performance.

Going from a quad with no HT, to a hex with HT, will give you a large increase in processing power in anything that you do.

That being said, isn't the VRAM on the gtx970 limited to 3 GB? Don't know about the resolution you play at, but that card may be at the VRAM limit.

Not anything. If all you do is use single threaded applications there will be no advantage. Plus they would lose native SATA3.

That said, if they do a lot of video encoding or production work (Photoshop, etc), a x5670 will destroy that 2500k, even at stock clocks
Switching would probably cost about $50-100 over the worth of their current parts, if they get a good deal on a board. A third stick would be good for proper triple channel (assuming they have two currently).

The GTX 970 can use 3.5gb of "fast" ram, the remaining ram is usable but very slow (~8800gt slow).
3.5gb should be enough for 2560x1600 for most games, most games will still be GPU limited at that resolution once you start pumping up the details/effects.

It's hard to know what difference there would be without a direct comparison, but I'm guessing it would be fairly minimal (less than 5%).
A pretty good comparison.

I personally don't think it's worth swapping out your motherboard to work your way backwards, even for a slight performance increase. Going for a i7-2600K or a good deal on an i7-3770K would make more sense. If you want 6C/12T, I would rather grab newer components (X79/X99) because it's basically a crapshoot grabbing a secondhand X58 motherboard outside of a forum. The safest investment for you is an unlocked Sandy Bridge or Ivy Bridge i7.

I think a 3770k is a pretty good idea if they really want to spend money, it can be had for around $200 on a good day.
But even then I don't think the performance will be much different for most games. A 2500k at 4ghz is about equal to a 4690k at stock.

Unless like I mentioned they do a lot of production work, then the x5670 could make sense on a budget (which is why I'm here :)).

I recommended an LGA1155 i7 because it's generally easier to swap one component compared to two. Any of these upgrades would only see a meaningful gain in performance in a select few games.

Yeah that's why I said the 3770k was a good idea.

Heres another comparison between a few CPU's.

Skip the dual core obviously, as it just isn't enough for this game. The 8 core 5960x does have a few portions that it really pulls ahead despite the lower clockspeed.
But overall the differences aren't that big and if the 2500k@4ghz is about equal to the 4690k, there is little reason to move to a different CPU or platform.
 
Well, after lots of playing around, was finally able to hit 4.0ghz on my Xeon 5650. Before, I was only able to get to 3.1ghz, but tonight came to the realization after reading page 3 of this thread, that I was overclocking the memory everytime I pushed up the BCLK, which in turn caused failures. Set the Memory speed multiplier at 6.0, and started pushing up the BCLK, with the CPU Clock Ratio set at 16.

Here are my settings now, if it helps anyone:
-----------------------------------------------------------
CPU Clock: 19x
QPI Clock: Auto
Uncore Clock: 12X (the lowest I could get it)
Base BCLK: 210
System Base Multiplier: 6x (speed is 1260mhz)
CPU VCore: 1.325v
QPI DRam Voltage: 1.34v
DRAM Bus Voltage: 1.64v

Turbo is OFF, have C-States ON

I am using a Corsair H80 cooler on it. I haven't ran Prime 95 or any other hardware burn test yet. My temps are in the low 30s, using Artic Silver 5 (made an X pattern with it, with a dot in each of the acute angles to get a nice, even spread).

One thing of note, though. I have a Sound Blaster Audigy gamer PCI card installed. It now makes crackling noises when sound or music is played... like static. Any thoughts? EDIT: Sound seems fine after the system has been on for a bit. Not sure why it sounded crackly on startup??

Thank goodness for this thread! I was really thinking my mobo was a piece of crap until I realized what foolishness I was making with the memory speeds! I am going to try to wittle down my voltage a little bit next on my VCore. Thinking I can get it closer to 1.3v or maybe lower. Any other suggestions? Should I try for even higher, or will it make much of a difference?

Turbo is OFF, have C-States ON

I am using a Corsair H80 cooler on it. I haven't ran Prime 95 or any other hardware burn test yet. My temps are in the low 30s, using Artic Silver 5 (made an X pattern with it, with a dot in each of the acute angles to get a nice, even spread).

One thing of note, though. I have a Sound Blaster Audigy gamer PCI card installed. It now makes crackling noises when sound or music is played... like static. Any thoughts? EDIT: Sound seems fine after the system has been on for a bit. Not sure why it sounded crackly on startup??

Thank goodness for this thread! I was really thinking my mobo was a piece of crap until I realized what foolishness I was making with the memory speeds! I am going to try to wittle down my voltage a little bit next on my VCore. Thinking I can get it closer to 1.3v or maybe lower. Any other suggestions? Should I try for even higher, or will it make much of a difference?

I willing to bet the crackling goes away when blck is a bit lower...not every board can go over 200blck without issues anyway. You should i think have turbo on and lower the blck to 200 possibly....you haven't even stress tested it yet and over 200 is much harder for most. your turbo will make up for the lower blck in a lot of cases. just my thoughts:)
 
I always had issues with sounds blaster cards during overclocking, most recently on my x58 and an X-Fi titanium. After a few seconds of gaming sound would just vanish, I ended up upgrading to the sound blaster Zx which is fine thus far.

It isn't card specific either, I have 2 X-Fi titaniums that both refused to work while overclocking the x58, both cards work fine in other systems.
 
I scaled back on my BCLK to 190, and enabled turbo. Put the multiplier at 20x, set the Vcore at 1.2875v. Running Prime 95 (12 hour blend). No more crackling on my sound so far. Temps are staying in the 60s (max has been 72 C) for the past hour. CPU speed on both CPUZ and Real Temp at 100% usage is 4.18ghz.

Stay away from X pattern method, I was thinking it was a good method until I took off my cooler from W3520 when I was putting in Westmere in. Instead of even spread I got a fuckin X blob on the cpu/cooler Arctic Silver 5 did not spread out.....

This is what I had:

The best way especially for these CPUs is a line method because the die is vertical:

You need to get the largest contact area possible, the heat spreader is soldiered on and is made of copper (nickel coated) so heat conductivity is excellent.

If an "X" is the best you can get, it will be better than a line as long as the contact surface is larger.

If you are keen you can delid or lap. Interesting fact, the Westmere heat spreaders are slightly concave whereas the Haswell-E heatspreader is slightly convex.
