Don't know Leeghoofd, I wan't to pull the heat spreaders off to find out, but I'm afraid of yanking off a chip too! Since they are not mine (this is a work pc) I'm a little hesitant....any recommendations on how to easily accomplish it?Quote:

BTW, I'd love to see some settings (volts and refs) you used on the "Pentium E6300 and Battle of the Caches revisited" 8x500fsb runs :D
Question guys....I'm running Orthos trying to find my magic numbers for stability. I keep passing large ffts, but hit the small ones about 17 min. in and fail. Any ideas what this indicates?
If I'm not mistaken large FFTs stress the memory subsystem while small ones stress the CPU the most and thus create the biggest heatload.
I think you should look at your CPU temperature!
Speed fan shows 61 core 59 core 1&2
I'm still trying to figure out Gtlr %
Working on 4Ghz 24/7 stable with good memory bandwidth and am having a little trouble. Currently on a Q9550 with G.Skill Pi Black DDR2-900 (8GB installed) and a GTX 275.
My settings are very close to stable, OCCT errored out after 3 hours 4 minutes one time and then after over 4 hours the next. IBT passes on standard settings each time, but I want to cure the OCCT error.
Any suggestions? This chip is taking more vcore than I'd have guessed based on the batch (L847C219) for 4Ghz, so any ideas to get that lower will be great :up:
After I get this profile 100% stable I'll go to work on 8 x 500 CAS 5, or until I get some OCZ LV or Gskill 9600's ;)
I'm also curious about vcore on this board. It seems I can adjust it up or down 2 settings without the loaded vcore even changing as read in CPU-Z/Everest. Even if CPU-Z doesn't detect a change, does the board actually give the chip slightly more voltage? I ask because I don't have a DMM worthy of measuring a voltage change that small.

Id drop both your cpu and mch skews back to 0ps first.
Mine does that too (2 clicks of vCore before CPU-Z shows it) Tool....it annoys the hell outta me. :down: Although my 9550's a C1, i use :
I also use .63 on MCH Ref and CPU Ref(anything over. 65 crashes). Your VTT seems low...I need 1.38 VTT and 1.38 MCH for 4GHz(471x8.5).Quote:

Doesn't BIOS go in steps of .00625 and CPU-Z .016 if my mem is working correctly!??? That would explain the gap/difference.
That could be, just never noticed it on any other board.Quote:

More vcore than I'd expected to use but 4Ghz with 8GB and nearly 10k across the board in Everest at only DDR2-942 makes me happy.
Now for CAS 5 500x8 24/7 stability :yepp:
<3 UD3P + 4 DIMMS occupied.
I have an E8500 E0 (have some decent potential considering voltage that he needs) + UD3P.
24/7 config is 3.8GHz @ 1.184V stable several hours in Orthos. (except VCore (lowered = undervolted) only voltage modified is MCH, 1.1 => 1.18, all others are manually selected at default value)
It seems i can't get a stable enough (for a benchmark) 4.5 - 4.6 GHz with resonable volts.
I tried next step over 1.400V (BIOS) for CPU, 1.57 PLL, 1.3-1.32 MCH, 1.3 termination and nothing, freezes at windows loading. I find it a bit odd since i sucessfully ran 3DM01 with CPU @ 4227 w/ 1.28V or smth like that. I'd like to hear some sugestions, untill i try some more tweaking.
LifeDrainer: Did you adjust CPU or MCH reference voltages? These will need tweaking for high clocks.
Yes, they were slightly over default value. I've read somewhere that 45nm C2D like not so high CPU Ref but i don't know how true this information is.
LifeDrainer, what FSB and multiplier are you using to try and get 4.5-4.6. CPU Ref can be left on Auto or it might like .785 (when VTT is at 1.20), but that's about it. MCH Ref depending on FSB most likely will need to be in that .70 to .74 range (again when VTT is at 1.20) for a C2D. Good luck and post some screenies so we can see some results!
EDIT: 400 watt power supply for 4.5-4.6 GHZ ??
Il show you all voltages, but at night since here in .RO now i have 35 degrees Celsius (=95F ?) in my room so is a no no for overclock. I was using 9.5 multiplier (480FSB). When i OC above 4Ghz i put 1 x Antec Tri Cool @ 2000 RPM to blow air near heatsink and one to blow air in NB direction.
PS: Yes 400W power supply, good one. My sistem can draw around 250W in peak with no OC. If i OC CPU + GPU it can rise but not too much, i doubt it can pass 300W so it has a lot to spare. I tested this PSU at my friend with Q9550 @ 3.4 GHz + HD 4870 and it worked perfectly with Orthos + Furmark both running. Lot of guys exagerate (a lot) when talking about PSU Units, a mediocre Sirtec 500W can take the stress from i7 OC-ed + GTX295, tested ;P.
Thank you for the feedback guys.
I want OC to 4.25Ghz.,but always stuck at the windows login screen.,i dunno what is the problem.this is my settings.,what should i change to get 4.25Ghz

bluestang, what MCH voltage was needed for 8x500 ? Any CPU/MCH Skew tweaks for it ?
PS: From where do you copy all values from BIOS and what is the tag to write them like that. Thanks in advance.
if anyone can help me i will appreciatte very much...
recently i flashed to bios F10e and tested it and didnt liked it as all my heavy OC failed, so i went back to F10b wich is great...but testing an OC machine rebooted and bios F10e recovered so now its the backup bios...is there any way i can make my backup bios to be F10b or the first one that giga came with ?
Thank you very much
Cheers all :up:
Sergio
still cannot get 4.25ghz.,already tried MCH latch to auto and pump vcore to 1.38125.,always hang at windows screen.,sometimes BSOD..try PL 10 also cannot.,does anybody know why..?

I would suspect you need more Vtt for the above settings, and you may want to try using the Memory multi's with D on them, not memory will function when using B above 400 FSB
mch clock skew. Should be at 50ps.Quote:

Sounds like it flashed your backup bios also, not sure how to fix that. I am curious to see how this turns out. I flashed my rev1.1 to f10e also and was unable to flash back to an older bios using qflash.Quote:
