1366 x58 Xeon Enthusiast overclocks club

I got bit by the new pc bug and built a kaby lake. The x58 is getting hooked up to my 55inch tv in my entertainment center. It's my backup rig in a pinch and tbh, a very good gaming platform. I think with a 1080 in it, it was getting BETTER FPS playing overwatch tha my 5.0ghz kaby lake with the same 1080. I blame windows 10 vs win7 though rather than the hardware.
 
New to the forum. Just found this thread. I'm upgrading an old i7-920 on a ASUS P6T to a W3670 that is in the mail right now while I ponder if I want to jump on the AMD bandwagon next year when they've ironed out the wrinkles.

I'm finding one of the hardest things on my current setup is the 6GB of ram. I totally wished I had bought 12GB at the onset, but who knew I was going to keep this rig for this long!

Anybody on these forums have any OCZ Gold OCZ3G1600LV6GK 6GB DDR3 3X2GB DDR3-1600 PC3-12800 CL 8-8-8-24 Triple Channel that is gathering dust in a shelf somewhere that they want to part ways with?

Ian

Good luck with that upgrade; I did the same thing on my Gigabyte EX58-UD5 last spring (also replacing a 920, even). I've managed to get it up to 4.3GHz (172 BClk, 25x) but it runs somewhat hot. I am planning a full upgrade soonish, and it's got 12GB of OCZ Gold in it that would otherwise go to waste. I'll keep you in mind in case you haven't gotten your hands on anything by then.
 
I have the same board, I stuck with triple channel because ram was cheap and I wanted over 16gb (3x4 or 3x8 were my options). That said, dual channel will work 2x8 if you want. Not sure if you have SSD but that plus Xeon and some ram and you'll feel like it's a new computer

I have 3x of these, but bought for much cheaper almost a year ago (I believe there is a ram shortage right now). https://www.amazon.com/Crucial-Ball...sr=8-2&keywords=crucial+ballistix+low+profile

I just found some matching ram on ebay for a decent deal, will go to 6 x 2GB. Now I just need to grab an X5650 or X5670 and I'll be set to play. I already have an 850 EVO SSD, had it for quite some time. I'm looking forward to playing around, I just don't need to buy a whole new rig right now. I don't use my computer for much anymore, and I go through these waves of wanting little upgrade projects, so this will be fun for me. Being way late to the game, at least I can find plenty of reading on the topic!

Grab a x5660 They are selling for 40$ or less right now on Ebay. They have the 23 x multiplier. I have found odd multipliers seem to be more stable, at least for me.
200 x 23 is 4.6 ghz. That is higher than most chips will ever do, so you know you will not have to run over 200 BCLK to get a good overclock.
 
So I have been upping my overclock from 4.0ghz on my system lately just for fun.

I am able to get it stable running Realbench for 4 hours with the following settings:

  • X5650 @ 4.4Ghz
  • DDR3 1600 @ 8-9-8-24 1T (1.65v)
  • QPI: 7.2Ghz
  • Uncore: x13
  • 1.392 Vcore
  • 1.355 VTT

When I am running the Uncore @ 16x, which gives me 3200mhz, Realbench will fail within 2 hours. What do you guys suggest I can do to keep the uncore running at the higher speed?

You're likely going to need to crank that QPI (VTT) voltage up a bit. I'm running 1.475V QPI on my X5650 because it's a garbage engineering sample (uncore locked at 20x, I'm running 3700mhz uncore) and I don't care if I degrade it. Maybe try 1.375V?

If you aren't comfortable increasing the QPI voltage up much more, I don't think you are leaving too much on the table with a lower uncore.

Awesome, thanks for the tip. I had actually bought an x5660 a couple of days ago, so we're on the same page! I was able to grab it for $32, a different seller than the one you linked. Looking forward to it arriving so I can start tinkering. I already updated my BIOS so I should be ready to go.
 
Got my x5660 in the mail today. I was super excited to experiment tonight, but then I came to realize that I don't have any thermal paste around. It's been 7 years since I installed this cpu.

In the mean time, I have been refreshing my practice on overclocking my existing i7 930. I updated the bios to version FH to get ready for the xeon. I had been running at stock settings for a long time, but I remember all the BIOS options and I have this thing clocked back to 3.8. It is much faster than I remember. If this xeon is a decent performer, I just can't see building a new system for a while. This is the longest I have kept a motherboard in use, it's a bit unbelievable.

toothpaste works just fine as a temporary measure for typical use

Ha. I didn't go to that extreme. I found some old white grease. Chip seems to boot just fine, but temps are high. Using my old Corsair H50 and I'm getting temps near 70C with stock settings. I need to get some decent thermal paste and re-seat the heat sink before I can do any overclocking.
 
yea you need new paste tho the chips do run kinda hot really once you push over 1.30 vcore.
 
Thanks very much for your very astute answer. I bought a x5650 for $32 and I was able to pick up some DDR3 (24G) for another $33. All I need to do now is decide on how I will cool it and if I wish to go "Water Cooling" with blocks on the CPU and both GPUs.
Any good cooling tips? Do you think it is advantageous to get a kit with water blocks for Northbridge etc? Since I have the 920 as a spare I feel confident in aggressively OCing the new CPU since they are so cheap and I can always replace it with the 920 temporrily if I fry it.
Again thanks for the response. I did not expect such a quick and well advised answer to my question on such an old thread.
Best wishes to all.
Even Hydro 60 will keep it more than adequately cooled, under full load you won't see Temps past 50-60c.
 
My main reason is I have an MSI motherboard (X58) and even with a bucket of KFC and my own blood to sacrifice, they hate going over 200 Bclk. So with a x5680, you get 6 physical cores, 12 with HT, 32nm process that runs cool as anything even under full load, and guaranteed 4ghz plus with a lower bclk keeping my MSI board happy.

Same, I have a cursed MSI board. You could hold its mother and kids hostage and it still won't do over 200 BClock. That was part of my reason in buying the 5680 for the higher multiplier. Also, odd BClocks work better, with 171, 175, and 181 being the absolute/most rock solid on the MSI boards.
 
I got a predator 360 and my x5660 is at 20x200 at 1.35v and it's reaching around 98c and then my system shuts down. I thought it would be more than enough for this CPU.

I'm thinking my water block is not making good contact.
The North Bridge is the Achilles heal of the X58. Took mine off and put new paste on, only made a 1-2c difference. Wish I could water-cooled it. Then you would see some 5ghz 24/7.
 
My temps are <60 C load and I can't get higher FSB, but I think that's the on chip memory controller because I ran 200FSB all day on my i7 950 with this board
 
Well the x5660 I received doesn't seem like it is setting any records. It runs 19x200 all day long with low voltages. It requires 1.30 vcore to run 20x200, and temps are getting up to 75-80ºC in prime95. It quickly fails prime95 at 21x200 with 1.35 vcore.

I have some better thermal paste coming. I'll try again this week. Was kind of hoping for an easy 21x200 but that may not happen. These things are so cheap, I may just try a few chips from ebay just for fun.
 
Man, I really lucked out with my p6t-SE - I can run BCLK up to 224mhz. Not bad for what was a budget board.

Cross flashed the Asus P6T WS PRO Bios to force 23x multiplier (although I don't use it).

Currently run the system 24/7 as my server @21x221 (4634Mhz) using 1.4Vcore, 1.4VTT. Temps get a bit high (High 80s using Prime using old Corsair Watercooler), but I could care less whether the chip degrades - I only paid $80 for it.

I'm jelly at your clocks, I think I'm going to have to play with my OC again :)
 
New thermal paste and installed the second 3 x 2GB ram set. Now at 6 x 2GB and 20 x 200. Vcore is at 1.30 and QPI 1.32 in bios. Temps are looking at low 70's in prime95. This thing is amazingly fast compared to my old i7 930.

I doubt I will get to 4.2 for daily use. It's going to take more voltage and my old H50 doesn't seem up for the task.

These are great temps. My 5670 runs 21x200 1.35v and my temps are low to mid 70's running world community grid. Cooling with a TRUE 120 and 2 gentle typhoon fans.
 
I grabbed a second x5660 from ebay as the first one I got was not performing at a high level. Holy cow what a difference between the two chips. I am running prime right now at 4.2 without even trying hard. The first cpu would not go above 4.0. And the temps are 10C lower with the second chip.

Current basic settings are 21 x 200, vcore 1.33125 in bios (1.296 cpu-z). QPI 1.335. Temps are mid 70's during prime. I'm going to keep dropping vcore to the lowest threshold until I settle.

This thing is like a new computer to me. I can't believe I did not do this years ago. Cheapest fun I've had since I started playing with computers!
 
Well I settled to 20 x 200 for daily use. I think the chip can do 4.2 if I wanted, but I'd rather not push the voltages. I'm at vcore 1.3125v (reported 1.28v in cpu-z) and QPI 1.275v.

Passed prime95 for 12 hours. Passed IBT for 10 passes on very high.

Is it worth dropping QPI voltage any lower? I read everywhere that under 1.35 is good and safe. I'd keep dropping it, but I'm getting tired of stress testing my cpu for 12 hours a day. Maybe it's time to just leave well enough alone.
 
just put my old water cooling parts on my x5675 can run 4.4ghz again without temps going thru the roof noted the old rasa block aint that great and im only using a 30mm thick 360mm rad keeps it in low 70s under full load now with 1.38 vcore.
 
nob question, sorry if it been asked before, this thread is just so long :)

i have a p6t asus mobo with x5675 cpu and 3x1gb ddr3 ram.
i would like to add 4x3gb. 12g will be enough so the old ram is not so impotent to keep.
i checked on ebay and it seems ddr3 server ram is much chipper
can i use ECC ram buffered/unbuffered with my mobo?
any recommendations / ebay links?

thank you all
 
with some tweaking i am able to hit 4.6ghz on 1.44 vcore now with my x5675 with low 70s for my load temps. Maybe less vcore and or 4.7Ghz will see as i test it more with much cooler temps.

You can't use ECC memory unfortunately. Though the cpu supports it, the motherboard does not. You're stuck paying extra for non ECC memory.
 
With my old H50 cooler, I could do 4.2 with HT off, or 4.0 with HT on. Any opinions on the better option for general daily use and light gaming?
 
ht on might be better if you dont game awhole lot the extra threads would be better for mutitasking.

Games like BF1 can typically use up to 50% cpu usage with HT On.....So with it Off, you could run into an occasional issue with the cpu hitting 100% usage along with the fact a few games here and there are coded to make use of it when available (Im sure it more of an advantage on duals and quads that can easily get cpu limited...but you never know) So with this being said i always leave it on!
 
Anyone with an X58A-UD3R (or any other board I suppose) have experience with Dynamic Vcore Adjust (DVID)? I am getting nit picky, but I am trying to do some final tweaking with my vcore. I understand how it works, and I have it set so my system is stable and adjusting vcore dynamically based on load. It reduced voltage at idle as expected. It appears to be functioning fine.

The only quirk I have noticed is that my GFlops in IBT are reduced when using dynamic vcore. When I run IBT with a fixed stable vcore, I get a consistent 63 GFlops. When I enable dynamic vcore, I get a consistent 60-61 GFlops. Anyone else experience little differences in IBT based on vcore settings?

Interesting, I use dynamic core but my computer is in pieces as I refresh the water loop right now. I'll have to check this out later, as I'd prefer better performance out of the ol' X5670!

Awesome, I would be interested to see if you experience the same results. For right now, I am back on my known stable fixed vcore.
 
Not sure if offset on my Asus is same as DVID on yours but it drops under idle will check IBT later. For my asus board exact vs offset in IBT didnt really matter funny thing i got like 6Gflops more running in offset then exact.

Very cool, I'm not familiar with the original thread, did they domnay application performance? What was the reason for no handbrake or time spy, just not having the software available?

In any case, this is cool stuff, great job!
 
Not to detail but just a FYI I have this x58 stuff for sell drop me a pm if you need it

I'm slightly addicted. Picked up an X5670 to see if it's any better than my X5660. Hoping for a lucky chip that will do 21 x 200 at relatively low voltage. More than anything, it's just a fun little project/experiment for me.
