1366 x58 Xeon Enthusiast overclocks club

Down clocking at idle all depends on whether you keep the various C States enabled in bios or not. Generally speaking, when you overclock you disable C states as they can mess up your overclock.

The x58 platform is multiplier locked with the exception of the turbo multiplier, meaning you overclock by increasing the BCLK. Overclocking x58 is tricky, but rewarding when done right as the platform has a lot of headroom. In the day I remember getting an i7 920 to 4.1Ghz remarkably easy, and that was the lowest spec i7 you could get at the time! The Xeon's are usually even better.

if you overclock properly you don't need to disable c states.

I didn't realize there was more than one way to overclock? It's been a while since I actually overclocked x58, but from memory it wasn't that hard to get a rock stable 4.1Ghz out of an i7 920.

If you want to use C states, go right ahead. Personally I can't see the point when the idea is to crank every ounce of performance out of the processor. Even on my current machine I disable C states and let the governor under Linux handle the clocks.

Do tell, good sir...if you know any good howto's on the process, please share. I'm not interested in max overclocks, something stable at around 3.5-3.8gHz would be good, with the ability to downclock as needed during idle and near-idle conditions.
 
What I did is I disabled the turbo boost but I changed the bus speed to 200 megahertz from 133 (x5660). Just basically treat it like a stock condition where it down clocks under idle conditions, but it will ramp up to full speed under load. I used an offset voltage and the voltage decreases at idle. This gives me 4.2 gigahertz under load and 2.4 at idle. The idle is a little high but it's not terrible.

I'm kinda with you there, which is why I'm asking about the ability to let the system adjust clocks as needed. I know TurboV will o/c *some*, I just don't know how much, or if it's even worth trying.

I don't know how far my system was o/c'n under Ubuntu MATE, but it would adjust up and down automatically. Of course, I switched back to windows 7 because I'm not quite smart enough to get either Steam or Minecraft running under Ubuntu 18.x. :shifty: *sigh*

Not terrible at all, esp with the right cooler.

How does the system handle the clock adjustments?

No issues. I forgot one thing. You have to adjust the memory multiplier to account for the change in bus speed. It didn't really take a big voltage jump to get up that high. Maybe 1.35 volts which you adjust from your stock volts in offset. I have used a dual Tower air cooler on it (scythe fuma) and more recently a 212+ and it works fine. X58 sabertooth is motherboard.

I actually disabled C states in BIOS, the only thing adapting my clocks is the governor built into Linux.
 
With C states enabled my X5675 will clock from either 1.8 or 2.06 all the way to 4.6ghz.

It idles at least 10c cooler with them enabled on my setup, generally around 28-34c with or 39-45c without c states/EIST.

What bios are you running on the X58 Sabertooth?
 
Okay, the holiday season crazy question of the year:rolleyes::

Have the Asus P6T_Deluxe populated with 12gig of this:
G.SKILL Ripjaws Series 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9T-12GBRL


Lovely stuff, works a treat.

If you'll notice, it's $74/$0.99 shipping. Nice price. <_< >_>

Question is: will it work? I've read about issues populating the second set of RAM slots on these particular boards. It does have the latest BIOS, and that sweet Xeon 5670 (did a series of file transfers over the weekend via USB that was smooth as silk & fast, faster than before the upgrades).

So, ye gawds of the X58? What say y'all?

Happy holidays, too.
 
I run 6x2GB and my x5660 runs like a champ at 4.2Ghz. so I haven't had a problem with 6 sticks.

But are either of y'all running the Asus P6T_Deluxe *specifically*? I keep seeing people with issues populating the second banks on those boards.

I have the asus x58 p6x58d-e with a [email protected] with 6 slots filled still not the board you have/getting but really any x58 should run 6 slots it usualy comes down to the cpu's imc and how much qpi voltage you need to push and what speed you want to run your unicore at. I had mine running 4.4ghz with unicore at 4000mhz using 1.45 vcore and 1.40 qpi volts memory also was clocked at or close to 1800mhz ran stable for atleast a year and fairly warm was lazy to pull it apart to do a new paste install and dust it out. I looked at both my board and yours and really only thing jumps out at me is mine had a usb3.0 added thru marvel and a sata 6 added thru marvel.
 
I am running an X5670 (Have a X5690 sitting on my desk) on an ASUS Rampage III formula. Its stable at 4.562Ghz with 1.45Volts. Would love to see some settings out there to get it higher or tweak the performance. My best Cinebench was 1038. I think that's a great score, would love to get to 1100.
Also, running 24 gigs of 1600 ram in triple channel.

Dang that is NICE. I wished I had pushed mine harder before I sold it to see how far it could go. :)

At this point that is what I am doing. Its not my main rig, its my experimental/hobby rig. I don't care if it blows up. Just an escuse to buy something else. :)
 
Dang it! I sold part of my ram and mobo..maybe I will keep my other 12GB of RAM and x5650 and find a cheap mobo to play with it :D
 
I have an odd issue thats been popping up. I've had my e5649 running solid at 3.8ghz for a few years, but over the past 12 months or so i cant overclock it all. I tried for a tiny overclock of 150 bclk and locking the core voltage at 1.25v, it corrupts windows when i try to boot. Takes a solid 5 minutes to load windows and then wont load my windows profile properly.

Think my chip is dead? time for 100$ for a 990x? ahhahaha
 
I'm getting an RTX 2070 (it was gifted to me) and I'm currently running an I7 920. Will my processor be a bottleneck to this card? If so I was looking at a W3690 Xeon (overclocking it) and was wondering if that too would be a bottleneck. Any help would be appreciated as I don't want to have to go to the expense of building a new system right now. Thanks
 
Also I was pricing the W3690's on Ebay and noticed most of the sellers are in China. Is it safe to buy from these sellers ( as they are in another country)?

save your money and get an x5670 for $20 instead. 22x200=4400 if you can keep it cooled. otherwise, x5650/5660 are even cheaper but it'd help if you have a motherboard that can reliably use the turbo multipliers (not sure if gb can or not) if you're aiming for an aggressive overclock.
 
I've got a Gigabyte GA-X58A-UD3R REV.1 it won't support the 5xxx Xeons only the W3xxx (according to their website). The W3690s are only about $60, which to me is OK. My worry is with dealing with sellers in China, and if the update is enough to mitigate a bottleneck with my new Graphics card.

Since IPC is basically the same from Nelahem and Gulftown/westmere you will only see an improvement in work flows that use more than 4 cores and that will apply to games also. The Battlefield series of games will get a boost as they can use all 6 cores. Other games you will have to investigate.

But are either of y'all running the Asus P6T_Deluxe *specifically*? I keep seeing people with issues populating the second banks on those boards.

I'm running the V2 version of that board. And using 6x2GB for 12GB of Ram.

The only issue i've seen is sometimes on a cold boot it will drop to 10GB's of ram and then I have to go into the bios revert to stock clocks reboot it then see's all channels then I go back into the bios and reapply my overclock and its fine.

That happens 50% of the time off a cold boot which I don't do very often so not really a shower stopper for me. And more so since i'm going to retire this rig for Zen 2 in Q2 of this year.

Should support it fine? As it turns out, I have the same motherboard heh. Not sure if mine is rev1 or what though.

Sure IPC is the same, but 32nm means less power consumption and higher clocks. I'm running 4ghz with 1.25v set via offset. No LLC so actual load volts is around 1.15vish iirc. If it weren't in a 24/7 server application, I'd push it harder.
 
I'm running a GTX 2080 with a Xeon 5650 on water. 4.4ghz 24/7. I game in 4k for the most part and I can say that there is no bottleneck. In fact most games consume ~20% of all cores under load (far cry 5 max settings). Which other games are you curious about, I'll try them.
 
Thanks bacon, that is good to hear. I'm just thinking down the road a bit, wondering when it will be time to do a new build. I think I will just see how it goes when I get the 2070.
