I'm still fiddling with my settings - been thinking about lower CPU vcore and higher memory bandwidth so I'm going for 4.1GHz, currently happy at 1.248 under load. The temps aren't even reaching 40C, it's crazy.

With the FSB at 432.5MHz I can run my memory at 1:1 using the EPP timings 4-4-3-15 2T but it's taking 2.17v to get it stable, however the memory bandwidth is very nice :yepp:

I tried it with vdimm at 2.15v but got an error, however increasing the vcore by one notch seems to have solved the problem - CPU now at 1.256v under load and memory happy at 2.15v 865MHz 4-4-3-15. I'm pretty happy with this.

Lenny,
Did you mod any of the other voltsages? What do you have your RAM at? I tell you, I have been so frustrated with this 680i and my E8500.
You have a great board and chip.

Yeah I have adjusted pretty much everything in BIOS to get this stable - here are my BIOS settings for ya:
CPU: 1.3000 ("current" says 1.26v, big vdrop)
FSB: 1.4v
Mem: 2.150v
SPP: 1.4v
MCP: 1.525v
HT: 1.25v
And clock settings:
FSB - Mem: Linked
FSB - Mem: Sync Mode
FSB freq: 1730MHz
Mem freq: 865MHz
And yeah my chip is very good, but to be honest I'm very surprised by this board; I didn't expect the OC to be such an easy one. At the moment I have do decide which is more important - mem bandwidth or CPU speed; if I crank the CPU any higher, I lose my tight timings with the memory linked to the FSB. I don't want to run it unlinked.
What settings are you using for your OC? There can be many things holding it back; I thought it was undervolted memory when in fact it was the vcore that was too low, so sometimes it can be a surprise.
Watch out for that fsb voltage, if you'll keep it like that I'm not sure you'll have it in 2009. :D
What Bios are you guys Using? im using the 1406 bios from Asus, witch should i use?
Thanks
Haha 1.4v is totally fine, it's only .2v over stock voltage. I can probably get by on 1.3v but I'm busy trying to get my memory stable and it's being a pain, so I'm gonna have to loosen the timings or run it with a different ratio.Quote:

While working on 533x9... I'd thought I'd try this... Not stable enough to complete SP 32M. (PL 10 with loose sub timings)
What should I chose from the below two (for 24/7)?
E8400@3800mhz@1.152LOAD (Temps ~67):

or
E8400@4000mhz@1.216LOAD (Temsp ~70-72):
Note: having this Vcore it will not be stable in IBT

Does 200mhz really worth additional 0.064v and +5C ? :shrug:
Thanks
I prefer 3.8@1.152 load. Prime load temps will be even lower and you may be able to run with medium fan setting. I don't think you could tell the difference between the two settings performance wise with day-to-day tasks.Quote:

I just tried E8400@4.0 and fsb to 450\9 and pushed the vcore to 1.32 but wouldnt last on Orthos so i gave it a little more to 1.36 and still wouldnt be stable...

Are you positive there's not some other sort of issue, faulty memory perhaps?
do me favor just stress the cpu and post a pic let's see how that turns out then we can go from there...it seems to me something is'nt getting the right volts:shakes:Quote:

and what board you on also?
I got +0.125v on the cpu volts to hit 4.0ghz and 4.1ghz and +0.250v on the DDR volts...
link to the pic of stressing both cpu and memory

orthos stress test at 4.0ghz only the cpu

Just updated to the recent version, im doing a Small FFTs - stress cpu with Orthos atm then ill show a pick, how long should i run it for?Quote:

my friend here's a sample of my other system in my antec 300 case now...Quote:

but he losened it up alittle to get pretty good oc out of a Quad core this what.I said
it will not allow at 4-4-4-12 it's to tight to at that oc on the cpu loos'en it up to 5-5-5-15 as 1066 memory and.I bet you get 469 and above..I managed to
with some Corsair XMS2 2GB (2 x 1GB) 240-Pin ddr2 sdramddr2 800

sorry about the shot Networking between Machines to take this shot here it is
from my antec 300 case with the ga-p35-ds3r machine with my E6750 alittle
oc'd had to 3.6ghz stable b4 turned it down sense was at 3.8ghz stable with
some Corsair Dominator 2GB (2 x 1GB) 240-Pin ddr2 SDRAM ddrs 1066 but took them out for another board...:yepp:
best a luck my friend and hope it works out..I plan to get some of that memory also later on there's only a alittle differents between the p35 and p45 bio's setup..i got a p45 gigabyte board under my bed right now ds3r..:yepp:
I was looking at the reviews of your Memory on Newegg Looks Good:up:
http://www.newegg.com/Product/Produc...82E16820231209
added to the wish list:yepp:
I ran it but my computer froze at 38min... :(
OK I've found optimum clocks for my system and it needs no more tweaking - 4.41Ghz at 1.352v load with fantastic temps. As a bonus I've got great memory bandwidth and I managed to get my vFSB down to 1.3v, so I'm a happy chappy.

Nice temps Lenny... very very nice, are you on watercooling?
Those are some fantastic results LennyRhys i only got my E8400 E0@ 3.8 any advice i wanted to get it @4.2 at least... i got a P5Q Deluxe also..
I have a Zalman 9700, not watercooling. :D: My case is closed up, all my fans are at their lowest setting, and even with the CPU fan at its lowest setting my temps only rise by 1 or 2 degrees. The chip just won't get hot lol.
What volts are you using to get your E8400 @ 3.8Ghz and what are your other system settings?
32M PI @ 4.698mhz
