You mean your E8500 vid will be different/change using say the x8 multiplier rather than 8.5 or 9 for example ?Quote:

Hmm, using the previous bios my E8400 did not change vid with a multiplier change. I'll try it with this bios later today tho.

im on the 30th place now with e8400 Oc to 5100Mhz

:)
my 8400 went from 1.0000v VID to 1.1125v randomly.
I hear you man. It's a shame too because if problems are brought to light, others can avoid them. Or if there are no real problems, then everyone can decode the mystery if they happen to encounter it.Quote:

Obviously board makers want to assure you that it's the chip and only the chip causing this behavior. They may be right, but I think it's fair to explore the possibility that there are other elements involved.

I'd be in 68th if I'd submitted a CPU-Z report :rofl:Quote:

nice cpu & memory thier necron66 !

Sweet score man. What was the memory you used for that? And the voltage on the ram.
I got 9.98 with a similar clock but at 8.5x545. I think I could get a better score with your ram.

Not only did I not validate it, before the run I didn't lower any subtimings, I think I could have got my 1st sub 10 run if I had of. No .5 multi's on DS3P unfortunatly.
It was done with a Zalman 9700 too, so it was pretty scary. :up:

i got it with 1.56 vcore on air
Heres an E8400 overclock I just tested overnight and during the day
http://i138.photobucket.com/albums/q...65x4951472.jpg
4.2Ghz(8.5x495) @ 1.47V.
Pls forget orthos... i cant be trutes since q6600...
Instead, use Prime95 v25.5/6...!
I use Prime95 sometimes, but prefer Orthos for the better GIU :P
No need for Prime95 25/26 on dual core anyway.
And E8400 under watercooling (20°)
http://www.pt1t.net/E8400/4_4ghz_1_41v_30min.PNG
unfortunatly , maxed to 585*9 under cascade ... 1.6v ...
+1 , me also on 2*E8500 and a E8400.Quote:

Just a heads up my VID reads at 1.050v, but after testing diff voltages in bios and comparing to the stock volt setting my actual stock vcore ends up being 1.125v setting in BIOS.
Why won't my DFI T2R just say what it is in bios...
Anyway, I tested by leaving DEFAULT in bios and seeing what CPU-Z reads... then I tried a few manual voltage settings in BIOS until CPU-Z read the same value.
So what's up with VID being read incorrectly? :(
Also, here my batch code and pretty much what my e8400 does:
Q745A741
D-Tek Fuzion custom mount, bix2 rad, 2xDeltas, D5 pump, Liquid Metal TIM
440x9=3960mhz @ 1.400vcore for SPi 32M stability
I tried pumping up to 1.425vcore and couldn't even do 441fsb (1 notch higher). My board ran 24/7 520fsb 3640mhz with my e6400 for a couple months, so I don't think it's the board.
I have another e8400 on the way that has benched 4.5ghz so I'll report back when that gets here.
Has anyone else had a chip that can't hit 4ghz? Raising volts has not helped me in any way. CPU-Z reads 1.456v right now and still I'm hitting a wall at 3960mhz.
Does raising any other voltages help much? I've tried raising VTT, NB and SB up a notch and it made no difference, but I'm wondering if they need to be raised more (don't know safe voltages and which are actually helpful).
I did disable vdroop and gained about 40mhz on the CPU at 1.400vcore.
@ gOdM@n,What divider are you running the ram at?
I have my E3110 up and running now,1.28vbios,1.29v SG, and 1.26x Load. 9x450 so far with a short Orthos small fft for 10 minutes. Just testing short bursts for stability then will run Orthos/OCCT tonight. She runs Hot, 44/37 idle, 53/53 Load. Vid is 0.9875v
More testing in progress, so far it is better then my E8400.
Larry
Just to be on the safe side I'm running 1:1 at loose timings of 5-5-5-18. Ram is 2x1gb Ballistix tracers ddr2-1000 @ 2.2vdimm. It's actually running like 880-900mhz on the ram, so that shouldn't be the problem... but then again, any advice is appreciated. Any other volts I should be messing with? I have adequate cooling... water... and big fans. :)Quote:

I haven't had a chip that wouldn't run 4GHz but I have found a few that either run hot on low voltage or cool on high voltage.Quote:

Goodman, how high have you had the vcore? Also, did you get this chip from someone else or was it like this out of the box?
I know it seems like you can't get high fsb but did you try 8x500 at all? How about GTLs auto or set manually?
g0dm@n - could just be a :banana::banana::banana::banana:ty chip. Just really odd that it requires 1.4vcore (just for SPI), and still not over 4Ghz.
Don't see if you mentioned, but what BIOS are you on? Not sure if it'll make a big diff though.
Has anyone tried priming with 10k FFT length?
It put's the most stress on my cpu. If my overclock is not stable the 10k fft's
will let me know within 5 minuts or less while 1024k's and 8k's will prime for
hours. Can you guy's try it? Im just curious if this is common on wolfdales.
