E7200 + ud3r oc

[B7ADE]

CPU: E7200 vid=1.1375
MB: P45 UD3R, bios ver: F9
RAM: 2 X 2G of OCZ reaper 1066(5-5-5-15)

So, right now im running at a FSB of 500 with a multi of 8 to get 4.00Ghz on my C2D. All the setting are pretty much AUTO(lol yea) except vcore which is set to 1.3475 in the bios(1.312 CPUZ). Right now my system is 100% rock stable and I wanted to see if i could go further on the OC. So I lowered the FSB and put the multi to the max of 9.5X.

Im trying to go for 4.15 with the following bios settings:

but within 45Minutes of prime small FFTs i get rounding error. Anyone have any tips or pointers to make this OC more manual and stable? All help is appreciated. Am i hitting the max for the cpu or am I missing some settings?

Thanks!

Re: E7200 + ud3r oc

You HAVE to set your own Vtt (CPU Termination), PLL, and MCH Core for your setup.

Your Vtt and PLL in auto is killing your processor so PLEASE Get those out of Auto now!!!!!

Once you do, find a stable point for them and you may be good to go. I'd suggest maybe 1.5-1.6 PLL and maybe around 1.28-1.34 Vtt

Just so you know, Auto is likely giving your PLL 1.85v and Vtt is likely 1.5+, which either can kill your CPU VERY Quickly

As for the rest once you get going, please post a screenshot of Memset so we can see what all those Auto's are giving you with your settings. Memset can be obtained here >>
Tweakers.fr

Ohh, you also need to set your own ram voltage, to spec

Re: E7200 + ud3r oc

I knew that AUTO usually overvolts but didnt know it would do it by that much, so i'll do that pronto.
heres the memset display:

Re: E7200 + ud3r oc

Thanks, now please after fixing your voltages set your own tRD (Static tRead Value) maybe 8-9 for now and then resume your testing. Once you get to where you feel you need more help post your full settings again, with new Memset image, and we will advise.

Re: E7200 + ud3r oc

Note that your memory might be under voltaged with auto settings and XMP disabled. Even with the looser timings BIOS sets it may still be on the edge.
Dispite common belief I recommand selecting XMP profile if you have it (the one that match DDR-1066 if you have more than 1,) it sets timings and voltage to match it's the EPP profile specs, and saves you the need to readjust timings for different bus/memory speeds and keeps timings close to the best possible.
After saving settings and reboot go to BIOS HWMonitor to see the memory is not over voltaged and adjust it manually if it is.
Check the sticker on the modules for their spec voltage and timings.

Re: E7200 + ud3r oc

thanks LSD and Chike!

I've got it stable now, but i have reason to believe that when it does fail it has to do with the temperatures(no im not running stock, but a push/pull 120mm fan modded Frezer 7 Pro) but i'll be getting my ultra 120 extreme on the 19th or 20th and thats when i'll continue pushing this beat of a chip forward. Thanks again!

Re: E7200 + ud3r oc

Temps shouldn't cause failure really unless you are getting really hot (80-100C).

You may just need a bit more voltage that you are not willing to give due to temps, hopefully your new cooler will alleviate that for ya!

Nice to hear you got it going though, post back anytime!

[B7ADE]

Re: E7200 + ud3r oc

Yeap, temps are about 91ish which i dunno why, my friend has the exact same setup/speed/voltage but his doesent go over 60...so lets hope theis cooler does the job.

[Lsdmeasap]

Re: E7200 + ud3r oc

Is that 91C? You sure you have your heatsink FULLY and Securely tightened down? If you are unsure please check. Did you maybe use way to much paste? What paste are you using anyway?

[Chike]

Re: E7200 + ud3r oc

I wonder if it's the E7200. Mine hits 73c (32c ambiant) with vcore/speed as in my sig with linpack tests, 10c less with prime.

[Lsdmeasap]

Re: E7200 + ud3r oc

Well 70 and 90 is a large difference though. I suspect he maybe has too much paste on, or the heatsink is not fully/properly attached.

Although I have not personally read many reviews of that cooler, I have seen many users with it and I do not remember anyone having issues with it being that hot.

[Chike]

Re: E7200 + ud3r oc

[email protected](in BIOS) vcore vs. 4.15GHz @ 1.4v is a large difference too. I tried 3.8 with 1.365v set in BIOS and it went well above 80c.

[Lsdmeasap]

Re: E7200 + ud3r oc

Hmm, well maybe those are hotter then I thought before? I guess since most have 8400 I am used to seeing it's temps

[Psycho101]

Re: E7200 + ud3r oc

My E7xxx series will almost litterally boil at 4GHz. At 3.9GHz, IBT temps are around 70c. When testing 4.0GHz (400*10) with the same voltages it shoots up to 86c, which is way too hot for me. It seems as if my chip generates excessive heat when pushed beyond it's capabilities.

4GHz on air is a little to ambitious for a E7xxx series. It's not received an updated stepping like the E8xxx series with it's E0 revision. A more realistic figure of between 3.4GHz and 3.8GHz is something to aim for. You may get lucky and be able to go higher, or, like me you may have to push more voltage (1.45625V) through to get stability. Fortunately the difference between 3.8GHz and 4GHz is minimal in almost all situations.

Starting with maybe 3/6GHz, you may learn more about what your particular chip likes in terms of voltages. From this starting point you can then apply what you've learned to a higher clock frequency. I usually just set the OC I want and then try and get it stable, but sometimes it doesn't work and you have to go backwards before going forwards again.

yes, i meant celsius. I think its a seating issue because I damaged one of the push pins and thats probably whats causing it. I dont think i applied too much TIM(I'm using AS5). We'll just have to wait until the new heatsink which uses the bolt through method.

Also heres what I have noticed in temperatures:
at 4GHz temps are at 71 max with prime
at 4.15Ghz temps are at 90 max with prime
The difference is due to the way higher volts need to stabalize the OC(1.264 vs 1.344)
