1366 x58 Xeon Enthusiast overclocks club

[EvilViking]

Picked up a x5660 for $18 to replace the i7 930. Gonna see what kind of overclock I can get with my x58 pro. Figure I'll give it to my dad to replace his i5 750 rig. Probably a side grade for him tho

Make sure you got the most recent Bios on the motherboard

 

[HighYield]

I'm in. My old Rampage III Extreme has been in service since release back in 2009 or there about. My son mostly uses it for gaming now. Picked up an X5670 on ebay for $31. Forgot that the i7-930 that it is replacing was 45 nm and the xenon is 32 nm. Going to be fun seeing what kind of OC I can get on that thing. It's satisfying picking up a processor that was ~$1400 at one point for $31.

 

[SSimmons05]

Ok, I have an old x58 930 rig sitting idle, am thinking about sticking a xeon in there so what would be the best xeon to get for 1366? Is it the 5690 ?

As they are going cheap on fleabay

Yeah 5690 is the end line.

 

[RAD]

Man... these chips are almost irresistibly tempting for me, since I am currently on a C0 i7 920. $30 to $60 bucks for an x5670, $120 for a used x5690 on ebay. However, googling my specific motherboard as relates to these fills me with some dread on this. I am running a Gigabyte UD4P, Rev 1.0.

I see tons of folks out there talking about how easy it was with a UD3R, and lots of folks out there saying the UD4P gives nothing but problems with these chips. The value proposition looks a lot sketchier at having to buy a mobo as well as a chip so I don't really want to go that way. Does anyone have a positive experience with the UD4P Rev 1.0 specifically and a x56XX chip?

What do you think about this Oculus rift support reply to an email I sent them?
Because their app to test your system compatibility failed my Xeon processor even though is way more powerful than the required CPU...I wanted to find out if the installer would not check that and let me install or not.

BTW, I did say mine was OCed to 4.5Ghz

Hello,

I am following up on your question about the compatibility of your CPU with the Rift.

The Intel Xeon X5650 is an older chip, released in 2010, and is unlikely to be able to handle the demanding requirements of the Oculus software. Even though it is a 6-core processor, our software checks for single-thread performance.

If you try to run the Oculus software with that CPU, we can't guarantee that the Rift will work properly or at all. This article explains more about the handling requirements of the headset.

You can find a summary of our minimum and recommended specifications here.

Please let me know if I can answer any other questions.

LOL I am thinking on a good reply to call him on his BS reply

At least the HTC non BS app said my system is performring well above what is needed for recommended high quality VR lol

I have a x5650 that wants a warm home for $4 shipping.

Damn, wonder if it would be a matched pair with the X5650 I have lying around.

Currently running a pair of HP Z800s with dual X5690s each.
Just got a free pair of HP Z600s from work yesterday, and have two matched pairs of X5670s ($55/pair) on the way to upgrade the current, crappy E5620s in there.

So now I'll have 4x X5690s, and 4x X5670s on tap (48c/96t of Westmere!!!) for any MT workloads.
I think my upgrade itch for Threadripper, Ryzen, HCC Intel, etc. just went out the window!

Greetings All,

I just registered with the forum to make this post.

First off, I've been aware of HardOCP for the last 10+ years, but it was recently when I found out that I could upgrade my i7 920 to a hexacore Xeon, that I read all 72 pages to gain info about this subject.

I ordered a x5660 off eBay for £25.00, and installed it into my Asus P6T SE without issue. I've been able to over lock it to 4.3ghz with help from the settings and explanations mentioned on this thread, so thank you to everyone that has contributed, this thread really is an invalauable resource for x58 and Xeon chips!

Now, the main reason I wanted to make this post is, I happen to also own an Oculus Rift with more then a dozen app/ games for it. I also run VorpX that allows me to play games like Witcher 3 and Skyrim in 3D/ VR.
I also have a GeForce GTX 1080 TI installed on my Xeon/ X58 build and a 4K monitor.

Now, for my testimony. In no way has the x5660 running at 4.3 Ghz held me back. I run games like Doom and Witcher 3 at 3840x2160 on Max/ Ultra settings and get over 60+ fps. I run VorpX VR and play Deus Ex Mankind Divided and Witcher 3 in VR running at 1440p and max out th refresh rate of the Oculus Rift (90Hz per eye).

Oculus VR titles like Batman Arkham VR, I am running 220% above the standard resolution (DPI adjustment) and was getting steady 90fps. All other demanding Oculus VR titles like Chronos and RoboRecall I can run at max settings, 150% DPI and both have a steady 90fps. Deus Ex MD VR experience also maxed out, 150% DPI and locked at 90fps.

Obviously, the GeForce GTX 1080 TI is doing a lot of the work in getting these games playable at these kind of frame rates and resolutions, I have the GPU overclocked to 2050mhz. But the £25.00 x5660 overclocked is not holding me back in any meaniningful way either.

I wanted to post this, so others that may feel an Xeon chip on an X58 is limiting in VR somehow, I have in no way found this to be the case. Equally these cpu's can quarterback a GTX 1080 TI and allow 4K, 60fps gameplay in the most demanding games released right now.

A GTX 1080 TI is also perfectly at home on an X58 motherboard.

Below is my TimeSpy score:
http://www.3dmark.com/spy/2035708

Hope this helps anyone that may have doubt the x58/Xeon combo isn't up to the 4K/ VR challenge.

Thank you all again aswell in letting me know there was a way to add more life to my aging x58 motherboard. I was going to upgrade to a Ryzen 1700, + new motherboard and Ram. This was going to cost me £599.
Now, I don't feel the need to upgrade at all, mainly thanks to the info contained in this thread. This thread is the jewel of HardOCP in my humble opinion.

Kind Regards and Cheers!

 

[candreyo80]

Just an additional update Regards Oculus and VR, I have purchased a copy of Lone Echo that's just been released.

Maxed out all settings including 4x AA and 200% DPI, again the game runs at a constant 90Hz. So there hasn't been a single game I haven't been able run at max refresh rate of the Oculus Rift using the x5660 @ 4.3 Ghz.

I believe the Oculus software only checks the CPU name against a predetermined list and does nothing in evaluating its real performance. If 3D Mark is to be believed though, a overclocked 32nm Xeon chip is well above the current needs for VR.

Thanks for sharing your experience. Yes I believe that it just checks some database of CPUs as well which is why I contacted them but then I got that completely BS reply. Of course I replied back ...waiting to see how they defend their bogus information now. lol

http://www.3dmark.com/compare/spy/2035708/spy/2001155# my setup compared to yours.....looks like my non-turbo config is way higher in cpu scores, but may not be the case in other apps.

http://www.3dmark.com/compare/spy/2035708/spy/2001155# my setup compared to yours.....looks like my non-turbo config is way higher in cpu scores, but may not be the case in other apps.

Yeah, the problem I have is because its a x5660, I cant access the higher multipliers and also the Asus P6t SE throttles the multiplier when 4 or 6 cores are under load. It seems to go back to 3927 Mhz when under full core load.
If I use a higher BLCK, the system becomes unstable.
I have been able to overclock the x5660 to 4.4 Ghz, and was able to run 3D Mark on occasion, but it would crash usually on other attempts.

I was able to get to 4.2 Ghz across all 6 cores using a 200 BLCK, using a non turbo multiplier of 21, but the system was unstable in Prime95.
Its odd, because when I had the i7 920 I've used for the last 5+ years, I ran at 4.2Ghz with a 200 BLCK, so I know the ASUS P6T SE is cable of operating at that high a BLCK.

I had to settle on a 187 BLCK with the x5660 using the x23 multiplier, and let it throttle back if 4-6 cores were used. With this, I can run Prime95 without crashing.

My QPI is as high as I want to take it, and the CPU is at 1.41V
I find also when I run all 6 cores at 4.2 GHZ, the CPU gets to 86-90C under heavy loads like Prime 95. This is with a triple fan radiator water loop and pump running 7.5lpm.
When I clock it to 4.3 Ghz but allow the motherboard to throttle back the CPU under multi core load, my temps hover mid 60C.

It may not help also that I have 30GB of DDR3 Ram installed, by two different manufacturers.
I did try overclocking with only 24GB (3x 8GB sticks) and couldn't get stable. I then tried just 6GB (3x 2GB Sticks), and couldn't get stable with this either. So I put all the RAM back in the system and gave up my aspirations of 4.2GHz across all 6 cores and stable in Prime 95.

I may very well be hitting the wall with this particular CPU, but for 25.00 GBP, I cant complain.
Any advice on stabilizing all 6 cores at 4.2Ghz with a 200 BLCK, I'm all ears

Cheers.

What exactly is your QPI set at? I had to use Max safe of 1.35 on mine...Also i never saw a Vcore over 1.34 beneficial to mine but then again im on Much older high end Air cooling...If i had a decent water setup then it be different. There IS a bit of a silicon lottery with these bad boys and that might be all it is as well.

I've set my QPI to 1.36125. I know this is over the recommended max safe of 1.35, but I did try lower settings, and would become unstable. I hoped that because it's only 0.01125 over max safe, I may still be alright. At worse, if this causes degradation and fails in the next year or so, the CPU's are very affordable right now, and I may pickup another that has higher multipliers.

 

[SSimmons05]

Thanks for the update on the VR! Great to hear with the right video card, our ageless beauties can keep us going at least ill the next Intel release, or even AMD's post Threadripper/Ryzen plans. Wonder if we will ever see a board as good as 1366 again?

We sure chose wisely when picking up this 1366 didnt we?

Probably not! I plan to get some 1.35v Crucial memory. I was reading reviews that people are getting 7-7-7-7-24 on them with a 1.5v......If I could get that with some new memory I will be 1 happy man!

Also do not forget you can use an M.2+PCI-e adapter for faster SSD Speeds. IT might not max out like it would on PCI-E Gen3, but its faster then the sata3 ports.

I have a 6gig adapter for my 3 ssd'ds in raid 0 and a USB 3.0 port for my boards adapters lol, only thing they needed to stay up to date, it's such an amazing system. Next year may be my only year to upgrade in the next 3-4 do to finances, so I probably will, I just am going to put my current one wrapped and boxed to pull and go on a moments notice!
I still read all the articles and reviews here have since the site was only 6 or so months old, but still have no clue which board/processor next year is going to be my next "5 year plan" lol.

For me Threadripper 16 cores is the one that caught my eye but somehow I need a system that at least can run all cores at 4Ghz for those apps/games that are not good with multi cores. I dont want to lose performance.

 

[SSimmons05]

Yeah I'm hoping AMD's next Gen now that they have the Tech down will boost each cores performance, as many things never hit more than 2-4 cores.

 

[Brackle]

It can. Samsung SM951 and the 950 pro series can be used as a boot device for X58. Plenty of people who tried and it does work.

When I did a research with my mobo at least, nobody was able to do so...and from the info back then I was told it was a mobo issue. If we can do it now, that would be a GREAT news for me.

You can still find Samsung SM951, and you can see a combo deal for $150 for it. https://www.amazon.com/gp/product/B00VELD92U/ref=ox_sc_act_title_1?smid=AHG2MI785YUY7&psc=1

Even in those posts people got it to boot with older P45 chipset. Looks like Samsung put in Legacy support into these chips.

FYI Samsung SM951 is an OEM 950 pro.

[Bill1024]

Reading that first link posted, it was post 230, he said twice the 951 does not work.
If any one gets one working, post back please
C&P


How is this possible? It doesn't recognize sm951 and as far as i know the 950 pro doesn't have an option bios rom like kingston hyperx predator.

For some reason in bios the 950 pro appears as an ide device but during windows installation, everything goes fine and windows install the nvme drivers.

I also did some benchmarks with the drive empty, before i could realize i could install windows in it. There is a cap at 1600mb/s due to the pcie 2.0 x4 lanes of the motherboard.

i disconnected the other disks before installing windows because i was afraid it might mess up my data. Only the 950 pro and the usb from where i installed windows.

You can see that it is an mbr partition table, not gpt, and that both system reserved and windows partitions are on the 950 pro and the boot flag is on the 950 pro.

I had an sm951 in the past and it would neither appear in bios when listing disks nor i could boot from it, so there's something different between them."

 

[LGabrielPhoto]

So guys...whats are your feelings about Threadripper so far...anyone making the jump?
I personally feel like waiting for a 2nd gen that can hit higher clock speeds, but maybe I will change my mind and get into it.

 

[Bill1024]

I do mostly BOINC and folding, from what I have seen not too many people are thrilled with the new AMD CPUs.
Their AVX instructions were not right before and AVX still does not seem to work nearly as well as AVX on Intel.
Some are having issues with some projects not running at all. So, I am waiting until they fix those issues.

 

[Napoleon]

Hi Gang-

Just did a rebuild including an updated watercooling loop, new Corsair 750D Airflow case, and GTX 1080 addition. During the rebuild something reset my bios, not sure if it was due to a power button issue I had with the case; regardless, I lost my settings and have been unable to get the build 'rock solid stable.

One thing I noticed is my northbridge seems to be hotter than previous, idling around 60C and increasing with use. I used to have a fan blowing from the side right on top of the northbridge but this case has a window with no fan; I'm debating cutting and mounting a 140mm fan blowing perpendicular to the northbridge but wanted to see if I can fix it with settings.

I'm up for completely revising all bios settings, I'm just looking for stability ideally with the similar CPU/memory frequencies I had from before. Perhaps I should test CPU only, then memory only?

Here are my settings:
Freq: 24x 175 BCLK = 4.2ghz
QPI: x36
Uncore: x18 (I believe 15-20 are ok?)
Memory: x10, timings 8-8-8-24-1

Vcore: Normal +.15625
LLC Level 2
CPU PLL - 1.8
QPI/VTT - 1.355
PCIE - 1.5
QPI/IOH score - 1.1 ( northbridge was heating up a ton at 1.16 so I backed off)
ICH I/O - 1.5
ICH Core - 1.1
DRAM - 1.4v ( ram is rated for 1.35 volts)

All cores/hyperthreading/CPU Thermal: Enabled
C1E: Disabled
C-states: disabled
EIST: Disabled

Old settings: I can't confirm but I think my uncore was 15 before (1.5 x memory ), 1.20625+0.15VCORE, 1.86 CPUPLL, 1.335 QPI/VTT, 1.16 QPIPLL/IOHCORE

I decreased some voltages but this morning the new 64 bit prime 95 found a 'rounding error', but windows kept operating fine. It said:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Self-test 640K passed!

Where should I start? Previous modes of failure were a program closed crash while playing Overwatch and another total system crash while playing Overwatch

By the way, my thermals are good, idles around 40c and loads around 60c

EDIT: perhaps i'll throw the ram multi to 8x and uncore to 16x and test CPU only. Should I test it at stock again? Since it was stable I'm hoping tweaking can fix it.

My notes from prior research say the IOH Core Voltage needs to be = to the QPI pll voltage for best results. Related to GPU loads, uncore stability. This suggests to me that if uncore increases, so must voltage. So if my uncore is up and voltage is down then perhaps that's an issue.

Is this still the standard approach for testing stability?
CPU - stock
CPU - max freq
RAM - max freq/timings
CPU - max freq and best RAM freq/timings

 

[Napoleon]

Well, stock it all primed fine. Now trying 24x175 with

Vcore: Normal +.15625
LLC Level 2
CPU PLL - 1.8
QPI/VTT - 1.335
Rest of voltages on Auto
QPI is only at 6.3GHZ and Uncore is 2625MHZ, trying to keep near the stock levels of 6.4ghz and 2666mhz - while i like this for testing, it'd kind of suck not to be able to push this a bit higher...

Not sure why stability has been an issue, could it be some other non-CPU/voltage settings?

I was running prime at 24x180 wtih a ton of voltage, like 1.39, but decided to stop that right as the comp froze.

I'm just trying to attain 4.2ghz stable with the lowest voltage possible, not sure what to do...

 

[mikecli]

Maybe it's summer. It might not look like it's overheating with OKish CPU temps but I still see instability when CPU reports max of 60 odd degrees under less than moderate stress in summer periods at an OC of 4.3+
4.2Ghz is pretty good already for a X6570.

I'm thinking I have to get a side fan vent mounted up, there is little airflow to the mobo/northbridge in this new case when compared to my Antec 900. My rads/reservoir block airflow from reaching the back of the case

Yeah I took my NB static cooler off and put on real TM, and it dropped the max Temps by about 7-9 C, though the dang thing still idles hot as well, think the non active cooled ones are the limiting factor on quite a few boards.

Passed 8 hours prime with:
24x170 = 4.08ghz
QPI x 44 = 7.48ghz
Uncore x 15 = 2550 mhz
Memory x 8 = 1360 mhz

C1E/C3/C6/C7/EIST all disabled
Mem timings 8-8-8-24-1

Have a very similar setup to Napoleon above, same mobo, same chip at 4.2ghz. I use to have a hyper 102 cooler that use to overheat badly when running stress tests at 4.4ghz.

I upgraded to a hyper 612 cooler and now temps are much lower... however no matter what I do, I cant seem to get it stable at 4.4 ghz, or even 4.3ghz, even though the temps are 70 during intel burn test on repeat.

Not quite sure whats going on, any input is advised. I'd tell you my settings but ive changed them constantly for ages to try and get a stable 4.4ghz again. Maybe my cpu or mobo just doesnt want to do it anymore even though temps are ok?

I have same board and CPU as Napoleon as well. It took multiple CPU's for me to finally find stability at 4.2 Ghz. I chose to utilize 21 x 200 as it gives a perfect 4.2 and my ram runs at it's exact rating of ddr 1600. My settings are as follows:

21x200 = 4.2ghz
QPI x 36
Uncore x 15
Memory x 8 = 1600 mhz

C1E enabled
C3/C6/C7 disabled
EIST disabled
Mem timings 9-9-9-24-2

Voltages:
LLC- Auto (it works for me)
Normal + 0.2625 DVID
QPI/VTT 1.315
CPU PLL 1.80
PCIE 1.50 (stock)

Dram voltage 1.5

I have to say that I tried about 4 CPU's total. I could use all the same general settings, but vcore had to be bumped to high on the others in order to get stability. I finally found this X5670 that would run 100% stable at a reasonable voltage and temps. Maybe your cpu has just degraded a bit?
