I have a i7 920 at that mainly runs at stock but can clock to 3.6ghz, I only have a 570gtx on 1440p, is it worth upgrading to one of these for gaming or stick to my i7 920. I plan on getting a 970 gpu.

I would say yes... I had a 920 that topped out at 3.8GHz, but my x5650 will do over 4.0 (I still haven't had time to fully test, plus I have a x5660 sitting on the desk).

I think everything runs a bit smoother with the Xeon... if I recall, in addition to the extra cores, there are also some other performance improvements (I think additional onboard cache).

You can then sell the 920 to reduce the total outlay.

IM running at stock at the moment due to a BIOS upgrade to support a new 3TB drive.

Im running Arkham Knight at 1440p maxxed out at 45fps average.... so ok for a while yet.

I personally think arkham runs well due to the extra 2 cores being able to run the god aweful DRM better than on 4 core processors. I got batman on release day, and it has always ran very well with no judders or slowdowns?!

I am staying with my current system for the foreseeable future, there is simply no need to upgrade the cpu!

I see you are running with a GTX980 G1... are their any system bottlenecks affecting the 980, or is it running a full potential. I did some research and decided that even a 980Ti G1 would work at 100% in a Xeon/X58 setup, but nice to hear some first-hand experience.

Hi guys,

I have one of these X5650's running in an Asus Sabertooth and was wondering if someone could lend me some of their findings regarding voltages.

I am currently at 4Ghz (20 x 200) with 1.2V on the CPU and 1.225V on QPI.

The rest of the voltages are all at stock. I tried 4.4Ghz (22x200) with 1.3V on both the CPU and QPI. It booted into Windows fine and seemed stable running some stress tests. But when I ran Dying Light it BSOD'd after a few minutes and upon rebooting it corrupted my Windows install on my SSD.

I guess this was obviously due to insufficient voltages?

To those of you running higher than 4Ghz, cant you possibly give me some rough idea what voltages you use?

Thanks

I'm running @ 4.4Ghz (22x200) which requires 1.35V in BIOS.

QPI is a shade under 1.3V IIRC

Thanks Kelt, I'll try that a bit later! Are you using all 6 memory slots? Am I correct in thinking that higher rated memory requires a higher QPI voltage?

Just using 3.

I'd guess filling the slots would require a higher voltage, but you could always try it first and see if its stable.

i am use 2 slots so i can oc ram to 2000mhz+ with qpi/vtt voltge 1.31v with Bclk 205

so yes more slots = more qpi/vtt voltage = more difficult oc

don't forgete Uncore is 1.5x ram not 2x so this will reduce qpi/vtt voltege

sorry for bad english

i see post say more cpu pll voltage will reduce vcore but i didn't try

xeon can handle pll 2.0v without problem

Anyone put one of these in a Gigabyte X58A-UD3R rev 1?

From a quick google it seems they are not supposed to be compatible with rev 1's but some people have been finding they run fine with them.

i have X58A-UD3R rev 1 & xeon x5670

how you know it is rev 1? see bios version and compare with gigabyte site

Is that under water?

yes it is custom water cooling

i see x5650 4.50Ghz with noctua nh-d14 so no say impossible

believe or not

i was have nh-d14 then upgraded to custom water the difference is 5c not as we hear ( 20c ) the experiance was with i7 930

anyone have a link to an overclocking guide on these x5650s?

I understand the basics but want to know which other stuff I need to "turn down" as I push the cpu?

just find a guide for i7 980x

see this link

http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-bloomfield-and-gulftown/

the most important you should know two things

more Uncore = more qpi/vtt volt

Uncore need 1.5x ram not 2.0x as i7 920 so this will reduce qpi/vtt volt and more overclock specialy with Bclk

good luck

Good to see this thread still going!

Mine is an x5670 at 4.5 on air. Gets toasty, but completely stable. Had it for 6 months or so now and it is great with SLI 970s.

I also have a rev 1 and works fine with x5650,the rev number is also marked on the mother board iirc.

I wasn't aware if this... why is the qpi link a different ratio for the Xeon compared to the i7 range? Is there a source for this?

DragonQ · 30 Jul 2015 at 10:59

The cheaper early i7s used 4.8 GT/s for QPI, whereas higher-end ones and all Xeons use 6.4 GT/s by default.

Fortunately, all of the Bloomfield CPUs worked at 6.4 GT/s anyway, which meant BCLK overclocking was possible even without a lower QPI ratio to use.

Is the 5670 just a slightly faster chip? Any reason to go for the 5650 instead other than price?

you notice gulftown wich mean i7 980x( it is same as Xeon X56xx )

if you want more sources

just googling by ( 1366 x58 Uncore 1.5x ram )

Sorry I mean Uncore
