Whats your Q9650 vid mate ? i got all templates from 4000 to 4900 on the Q9650 just to try, but tell me your vid plz

Cheers

How does one determine the processor Vid?

Coretemp or Realtemp will tell you the vid. In Realtemp under settings check the box "VID Information" in version 3.30beta

I'm getting problems with my PC just spontaneously rebooting when running linpack with 1.45vcore or more. Tested at 400x9, which is linpack stable at 1.344v, if i increase voltage to more than 1.44v PC will reboot after a couple of minutes of linpack I previously thought it was my PSU not providing a clean enough current, but after buying one for £95 (corsair TX750W), it still does it. Does this sound like my VRM's are overheating? Any help or advice will be appreciated.

EDIT: oh and it's not CPU temps, max i got during linpack was 78c which isn't enough to make my pc reboot.

May just mean you are not stable. Try some blend, if it passes prime blend it is possible that the high temps are causing it to crap out and reboot.

Just got my hands on a q9650, IIRC, same batch as you ocnub... L847C037 with a vid of 1.15.

This replaces my old L826A965 with a vid of 1.25.

I'm excited. I'll post as soon as I get it.

hopefully it will do a bit better than the old one.

Hi thanks,

I'm pretty sure the memory sub-system is stable at 400x9, i gave the NB a bump anyway just in case. I only found that it kept resetting when i was trying 3.8ghz on linpack with 1.45vcore (passed prime95 small ftt's for 8hours). That's when i tried 3.6ghz with the same voltage, and it resets on linpack when vcore is above 1.45ish :/ It normally does it on the 3rd test (other tests passed as well).

Anyway, will be getting a 45nm quad soon so most probably won't have to use above 1.4v, and temps should be better.

ps. Is it important to keep VTT close to vcore regardless of FSB? as i was using stock when i was trying 400x9 with 1.45vcore.

Awesome vid, Congrats. Hope you have great success with it.


Oztopher, I am not familiar with the q6600 but I try and keep the vtt below 1.360v for daily use on my 45nm quads. I know with the q9650's anything above 65-70c will cause it to become unstable, thats why I thought it may be the issue.

[Oztopher]

Ahh i see, thanks mate

Guess i'll stay at 450x8 for now then, until i get my 45nm'er.

I really hope I do. I feel like I deserve it after chasing you two...

where the heck did you find that batch?

[nkresho]

I've had my eye open for it since seeing what ocnub has done with his.

As soon as I located one (another forums f/s section), I bought it. It happened to have been a seller who I've dealt with before, so I was quick to pull out the cash.

[The Viper]

I found some stability at 4.2Ghz

[OC Nub]

Your mch ref looks to be a little high. Try it at .80 with default cpu termination of 1.20 then raise the termination back up to where you are now. I always default the cpu termination to 1.20v then set the refs. Everything else looks good, nice job.

[Machinus]

I need help...I am not sure what I am doing wrong but the chip is a little warm and the FSB just won't budge. Can anyone improve my settings?

Machinus, I really think you need more MCH voltage...also what is your PL set to?

What do you mean PL? Why do you think MCH is too low?

[The Viper]

Performance level...its known in the BIOS as Static tRead value under in advanced timing control...also what RAM do you have...you should put your system specs in your signature

Your MCH might be too low based on what Ive seen from other setups in this thread...you might want to take the time to do so, as i did, at least from page 50

Static tRead is set to 8. RAM in sig.

Your reference voltages for CPU and MCH are off. try setting default vtt 1.20v and try .785 cpu ref and .80 mch ref, then raise vtt back up, leaving ref's alone. a bump up or down a notch can make a difference in stability. The other ref's leave auto until you get some stability at your desired oc, then learn them. You may need more mch. You will probably be able to lower vcore and vtt with the correct reference voltages.

If you take the time to look through this thread all the answers are here.

Downloaded RealTemp vs 3.0, cant find my VID.

Where in the picture the VID is located I have a time counter going up.

Correction.

VID is 1.25 at my clocks in my previous post, I do not know if my voltage modification has changed or if it is possible to change my VID.

Your vid never changes, it will always read the same, check cpu voltage with cpuz.

[nkresho]

lets play yeah

I'm in now. Chip should be here Friday. I already have the ram (gskill9600 PI) but the board is an ud3R not a ud3P though. We'll see. I expect good things. I really want 4500 stable for daily use (under 1.4v in cpuz). it should be simple after dealing with this high vid chip.

I'm going to be adding another radiator in the process too. Right now I'm cooling my gtx285 with a koolance fc block inthe same loop as my pc on a dtek v2. I'll be adding a mcr220 to my current mcr320 for added cooling power.

I'll post pics of my new baby when she arrives.

I'm on vista 64, do you guys think I'd see better oc results from 7?

I preordered already for this machine, just waiting till release. My real issue with it is that I play bf2142 pretty frequently, and I've read it won't let punkbuster work properly with 7 (it sees it as non-retail o/s and kicks you a lot).

nice i wish you luck mate, also nice to have 2 loops

yes W7x64 better than Vista inmo

Cheers and post when you got it so we got some play time
