Hi there guys, i'm running a Asus P5Q Deluxe with an E8500 E0 and struggling to get it past 4ghz, can anyone help me out with what to set in the bios( maybe someone has the same mobo and chip)
Thanks

Try posting that in the Intel section, not in this thread to keep it on topic :)
People need more info like what you are using, RAM and speed, volts, vtt etc. also what cooling. but id suggest making a thread in the intel section if u want the answers :)
Ok here are my specs , Q829A on the E8400 , and you guys will prob laugh but Im all on air !
GA-EP45-DS3L
2x1gb Corsair DHX 800 C5 @ 1066 5-5-5-18 2.1v
HD4850 @ 725 /1187
E8400 1.392v 4530mhz @ 533 fsb(2132) 1:1 idle 34/37 orthos 54/58
13,970 3d06 , 10s superpi 1mb 10min 32mb
Antec 300
Antec Trio 650 psu
Xigmatek HDT-924 w / Dual 92mm 60cfm brushless fans.
Accelero S1v2 w /dual 110 72cfm brushless fans
I've been confused so far - I've had the pleasure of owning 2 E8500 (one C0 and 1 E0) and 1 C0 E8400 - plus my current e8600
And not one of those chips would even think about being stable at 4.5ghz - I tried up to 1.45v and to no avail - its not an issue of FSB by any means
All kinds of people are hitting 4.5ghz on much lower voltages and I'm not even stable at higher .... ??? :shrug:
am I just unlucky ?
Believe me it is'nt that bad bein on air as long as the Temp in the house stays cool..In the summer..i keep my house central air at 69c all summer long but my rig is sitting under a air vent so my two 120mm's blue Led's are sucking in the central air :yepp: the volts on your cpu is kinda high..I guess it will be on a gigabyth board but there boards have VDrops..I got mine at 1.350 in the bios but it dropped to 1.312 sometimes 1.280:yepp: oc'd 3.3ghz that's all...Is that a CO or a EO stepping you got? try not shot and hold to much volts to your cpu 24/7.i would'en like to see you run back to the store buy another:shakes:..I know the E8400 is rated at 1.362v maxQuote:

I'm pretty sure the link below will help you out if you hav'en been there already

Don't get the reference - that is for a P45 board - while I have the P5K DeluxeQuote:

There has been a new bios release for P5K board, so maybe Dlx will follow shortly...
Thanks man! :)Quote:

Ok went for my 24/7 power/performance/temp setup and am tweaked down for benching now with this chip
I only got it 4 days ago, and have a family and limited time to tinker lol :( though over 25+ yrs Ive had plenty.
Final settings in sig. I like that it does not get more than 10C hotter under full stress configd like this
Now onto the hardmod on the 4850 ! All cooling fans , heatsinks, and ect.. in place already , just have to find
a variable resistor to put in.
on the nb i have a small 40mm fan on the heatsink - running 100% - i have a temp sensor on that and even during 560fsb stress testing with the nb volts cranked up my sensor probe never hit over 50c which isn't bad as i had it cranked to 1.7v for those hoursQuote:

now ln2/dice or chilled water - that might be another story with sub ambient temps
not sure if the board is the issue - I'm running 24/7 atm at 560fsb on 7.5x multi ofr 4200mhz - at 1.55v on the nb - about 1.392 vcore - 2.15v on the memory at 1:1 4-5-4-15 t2 - i think i have both gtl settings at .61x - transaction booster enabled at lvl2 - fsb ratio at 333
Need some help...
Currently attempting 562 x 8 = 4496Mhz @ 1.4v
E8400 Q829A234
Large FFTs stress survive more then 5 minues
but Small FFTs failed after 55 second (First Loop checkpoint)
stating Final Result Mismatch (rather then common rounding error)
Hardware as sig...GTLs all -50mv, NB GTL +40mv
what else should I try? vSB & PLL @ 1.61v VTT @ 1.28v
535x8 = 4280 Mhz pass 6 hrs ORTHOS @ 1.304v load...
They do, picked up an e0 e8400 from tigerdirect for $199 just yesterdayQuote:

is that piece good for o/c?
looks like and old batch....
I have no clue if this is EO or not mate, only E8500 in my list that are EO's are listed from Q820 on.... make sure you get an EO model...Quote:

should i buy an 8400 or 8500? the mobo i have is "DFI LP DK P45-T2RS Plus"
you cant go wrong with either chip as long as it is a E0 stepping. the CO stepings are good but the newer EO stepping will let you OC easier with less volts.Quote:

E8500
thanks bro...
i will buy tomorrow an E0 stepping 8500
yes, my C0 3970 stabe. at 1.4 v
The E0 is much better
i buy an 8500 finally with batch Q746A580.
i will post some screen shoots later

but it is a good OCing chip so you should be ok with it getting a good 4.0ghz OC.
Anyone seen Q836A368 yet? (e8400)
Got one here to test this week :)
Q836...? This is fresh... :)Quote:
