$$$ in the bank, my measly 4.0GHz e6600

[p8ntslinger676]

Well I just installed my e6600 yesterday and finally got done reformatting and installing windows today, so I just spent about 30min overclocking it and got it up to 4.0GHz, I know I can do better, but it will come in time. Ill probably do a little more later, Its under water and im waiting to buy a mean well psu and mill a cold plate then I will be able to push it quite a bit more with temps below freezing

progressive screenies starting at stock clock:

Week? Voltage?

Nice.

Nice.

ill check in bios one sec. my in windows monitor isnt very accurate.

v core is @1.61v

I think my 500watt ultra x-connect is having a hard time keeping up

is 4ghz max?
what r your temps on the water?

do you have weeks steeping?

no its not my max, but I havent tried going any higher but I know that I probably could, the wierd thing is my idle temps are between 45-47, but I just reinstalled the wb after using some fine grit polishing compound on it so it very smooth but im thinking that the polishing compound might acctually be hurting me temp wise cus they seem a little high, and im using a Eheim 1250 with a 120.3 but the outcomming water from the wb is not very hot, but then again I did just reapply the as5 so it might take some time to set up correctly but I dunno on another note, when ever I try run prime95 it restarts but it runs super pi perfectly fine, wtf? and what does weeks steeping mean?

[justin_c]

week? 30 something? a or b?

edit: sorry missed that line. heres a explanation.

something like this : L6##X
## is the week
X is the the stepping. not to be confused with B2 stepping, all conroes are B2 and all ES conroes are B1.

for example, L627A - 27th week, A step.

[EnJoY]

Look on your box near the barcode. It will say something like L6XXXXXXX

Where the X's are the week, followed by an A or a B, and the batch #.

[p8ntslinger676]

nvm I found it:

Batch #=L631B106

So its week 31 B

[wtkprol]

Ahh, ok. I have a 31A and was trying to compare thanks.

so no one wants to answer my question about why I cannot run prime 95 with out it rebooting immediately?

[CedricFP]

Because it is not a stable overclock.

Prime stresses the CPU, and if it isn't stable it will either lock up or reboot.

(I am assuming you are trying to run prime at 4 GHZ).

yes, I guess I need to get to work then and try and make it stable , any suggestions?

Lowering down the clock speeds would be simple... or get a vapor phase change unit to cool it

Ok so try 3.6 ghz, 3.7, etc. and see where to go from there.

[[XC] gomeler]

and if it isn't stable with 1.6 volts and you are sure your memory isn't an issue, it probably needs more vcore but then again 1.6 is quite a bit for water, atleast imo.

[[cTx]Philosophy]

run either large or smaller fft,s to see whats ur major concern area, then ull know if you need more of less here or there..

Power supply, stupid POS ultra 500W killed my badaxe2 within 30 seconds of powering it up.

[shifty803]

Yeah, run two instances of Prime95 (one on each core) or Orthos small FFT for 8 hours to check for processor stability. Another thing I like to do is a quick 3DMark05 run, and if it reboots or gives you a cpu mark score of like 2000, it isn't stable

memtest86 is good for figuring out your memory capability to rule that out as a problem.

4ghz prime stable is going to be a hell of a feat without subambient cooling. My e6400 will only do 3.88ghz prime, but i have pi shots up to 4.16ghz. dual 32m @ 4ghz and 1.58v with a storm, mcp655 and mcr220. Sounds like you have a good chip though.

thats not true and im not sure where you think subambient temps are needed. its gunna help, you bet. but needed ? nah.

air is gunna be hard water easier. especially at 1.6v or more. the cpu temperature is way into the redzone on air at 1.6v i dont care what kind of air cooling you have, your stressing that cpu hardcore. unless of course you have it sitting right next to an open window and its 30F degrees outside.

now that being said its very doable with the right mobo, cpu and ram.

4g at 1.6ghz is average for the good chips.
even my beloved B1 Step 5 ES takes 1.6-ish for 4g.
its a very doable thing.
dont discount someones overclock so quickly.

if your system is rebooting instead of just failing prime, its a very unstable overclock. and you need more vcore or more chipset volts or lower your ram down. i say vcore. but i dont know.
its hard to say right now with what limited information you have supplied.

[gundamit]

See if you can snap off a 32M runs on both cores to see if its anywhere close to stable. Then move on to 3D, then finally Prime for your 24/7 settings. It would be a nice bonus to get details on your cooling and CPU temps while both CPUs are under a load.

[StealthyFish]

I wouldn't count the power supply out of this. There might be something up with the PSU. with overclocks, you push every part in your comp to the limit, PSU included. That PSU could hinder your OC pretty significantly or destabilize it. For now, I'd lower clocks and move vCore a little bit away from 1.61V (IMHO, 1.51V tops for me) and start looking for a more stable power supply or if you've got an extra PSU lying around, try that.

[Kakulukia]

I doubt that it is the 2less voltage that makes it reboot.
I have also reached that FSBx9. And i can tell you, it is not stable. Even with the maximum voltages.

Try 400x9. Then configure the voltages as stable/cool as possible.

Btw, set Nb to 1.55, SB to 1.7 and Vfsb to auto.

(you re tellin us that u have done this in 30 minutes...... thats enough to say :unstable.)

[xlink]

several things to note...

your PSU is sufficient for a midrange non-OCed system...

a 4GHz c2d is a lot...

you need a better PSU.

as for everything else, notch the CPU multi down, prime/orthos test on large FFTs to check your RMA/chipset. if it fails, it's either the board or the RAM.

and at this point if you're running 24/7, a stable overclock is better than a higher one for day to day, that extra clock speed won't help you browse the web any faster.
