Kentsfield Woes

[wwwww]

Using the P5WDG2-WS Pro with a QX6600.

FSB is stuck at 310FSB, no higher is stable.

Can't raise the multi higher than 9x. Flashed on a beta bios which opens it up to 20x, but it doesn't post at anything above 9.

Any ideas?

Temps maybe? not enough volts? might have to face that its just a crud OC cpu

[Lestat]

wth is a QX 6600 ? you mean an E6600 ?
and what week and stepping ?
what voltage ?
what psu do you have
what ram
what everything

come on guy ya gotta help us out if you want us to help you.


so lets start with the most obvious here.

you have a 6600 there is NO upwards multi that is ONLY for the X6800
where how and when did you think you got anything more than 9x ?

Kentsfield ES - QX 6600

[milkcafe]

here is a QX6700 thread
http://www.xtremesystems.org/forums/...d.php?t=106324

the QX6700 means

4x Core 2 Quad Xtreme version E6700

and so on ...

[theteamaqua]

its Q6600 i think, not an extreme edition

[sierra_bound]

All Kentsfields are Extreme Edition processors. Another member had a 6600 Kentsfield. He was using a P5W DH.

in response to the original post/question:

you will find that different boards/BOISs respond quite differently to each individual kentsfield. don't forget - you're dealing with an Engineering Sample. i have seen some quad cores that will go to 400 FSB (only one actually) and many more than struggle anywhere from 300-360FSB. you'll more than likely need to test that CPU in many, many different environments before you find one that satisfies you (what do you think the MB manufactures are doing with theirs?)

Only one?

I think current Kentsfield record is 450FSB.

[blossa]

9x310=2790MHz. That is what you can run at the moment?
Atleast 10x266 should be possible without raising vCore. But just to be sure, put the vcore a few 'steps' over stock voltage.

I am not sure, but was there not a 'lock' somewhere in BIOS that keeps the standard allowed multiples? I will check that later.

Is it BIOS 0004 or 0005 that you are using at the moment?

sierra: Nice result! I can not get my B0 over 220 yet.

well you heard it from one of the few guys around here who knows what the kent's are like. and as usualy with FCG i'd trust his word.

[wwwww]

My main concern is that it doesn't post at higher multipliers. If it does 2.8GHz normally, it should do at least 266*10. Temps are high 40's. Tried 0004 and 0005 - both the same problem.

I've tried heaps of settings and it won't post above 9. How is everyone else posting above 9?

Is there any way to change the multi in windows?

I'm about to try with vcore @ 1.4375V

Still no post at 10

[eva2000]

try a different motherboard

[wwwww]

try a different motherboard

Yeah might try a P5B - apparently that lets you scale the FSB on these Kents really well...

so this is false:

???


no Q6600??

[wwwww]

So the 6600 isn't an Xtreme edition?


This one could raise the multi:

Mine has the same revision as his and appears the same in cpuz except that mine says it's an ES...hmm

Also note that only die 0 will change multi over stock 6-20 for both cores, die 1 will stay at 6-9 range (for 6600s) and 6-10 range (for 6700s) for both cores, this is only relivant to ES I beleive.

[Anemone]

That mobo can go higher "normally" on a Conroe. Kentsfield is going to behave differently for sure, but you may need to consider the ram your using, and that the P5WDG may not like it.

The heat goes up fast on Kentsfields oc'd, so I'm guessing you've used the multi to go up to test how far the cpu is capable of first yes?

The Q6600 ES "should" be open multi yes. But bios can limit this - have you updated the bios?

All thoughts to consider

Well right now I can't change any dies.

Board does 458MHz with my memory on my E6300.

I can't raise the multi at all. If it does 9*300, one would think it'd do 266*10.

Well I've tried all the beta bioses that actually give the multi option.

All the quads will be xtreme edition, they'll certainly be priced as such imo

[Anemone]

Something definitely odd about your ES...

then tell me , these articles:

A mainstream quad-core Kentsfield will launch early next year, dubbed the Core 2 Quadro Q6600, and will debut with a 2.4GHz core frequency. A price tag for the Q6600 has not been set yet, but the processor will retail for less than the QX6700 but more than the Core 2 Duo E6700. The E6700 has a street price of approximately $530 USD, but price cuts will bring the cost of the CPU down before the Q1'07 launch of mainstream Kentsfield.

are false??

as for why 6600 has unlocked upward multi. 2 scenario:
1. all kentsfield have upward unlock multi.
2. maybe b/c thats an ES??

i hope its the 1st one ... and i hope there is a Q6600

Yeah tried that - tried 0004 and 0005.
