e6300 clock and temps..

V|per · 2 May 2007 at 14:52

Righty, was going to sell this on as i have an e6600, but though't i'd have a little play after seeing it was a L628B stepping, booted up fine, running a zalman 9500 with mx-1 paste, idled at 35c and loaded to 45c (this room is VERY hot, gets the sun all day long) so i was fairly happy with those temps.

Went into the bios and left everything on auto except the memory fsb was on unlinked (at 400mhz 4-4-4-12-1T)

Upped the fsb to 300, tested for 30 mins, great, no problems, temps maybe 1c higher than at stock, back into the bios upped fsb to 333, 30 mins of orthos was fine, but the temps jumped crazily... 50c idle and 67c load :eek:

cpu-z was reporting the voltage at 1.126v.. about right for stock with loaded vdroop.. (stock appears to be 1.25v on this chip...) checked temps with coretemp, tat, speedfan, pc wizard, all the same... went to the bios' hardware monitor to check, they were the same too... but it now said the voltage was 1.4v surely the board doesn't adjust the voltage when overclocking???? (it was on auto, rather than manually specifying it..) anyone else had this?

Anyway, manually set it to 1.325v, tested, temps are now 38c idle, 50c load.. happy with that

Back into the bios, 366mhz fsb, tested, fine... 400mhz fsb, tested, fine... 433mhz... thesting now, and so far is fine after 30 mins... damn this is a nice chip.. would love to hit 533mhz for that loverly 100% clock

Just wondering how other people are getting on with this stepping?

Will keep y'all posted..

Cheers,

Phil

Well if i am reading the outer packaging right on my CPU, i have the L632A stepping (FPO number on the box) and it seems like quite a good chip.

Running it at 450MHz no problems so far, idling at 40 degrees with a Scythe Ninja Rev B and MX1 paste also.

Have tried increasing the FSB higher but no luck, opened this thread for help:

Gonna try the suggestions and see what happens

Recently bought some Crucial Ballistix ram and tried overclocking my 6300. Is there a way to find out what stepping the cpu is without the box? cpu-z just says the stepping is '6'.

Got it stable running at 450mhz fsb with the memory at 450mhz 5-5-5-15 on stock volts, Motherboard is a P5B-Deluxe.

Incidentally, isn't stock voltage on the 6300 1.325v? Kind of hard to tell with the vdroop on the P5B. I have it at 1.35 in the bios but both cpu-z and speedfan show it as 1.3v. I'll try upping the voltages and see if I can hit 500mhz, I did try it on stock volts but Orthos failed after a few seconds.

stock is 1.325v, thats why i was confused to id defaulting to 1.25... you can also tell the stepping by reading the CPU

but that means you have to get the cpu out :/

schumi84 · 2 May 2007 at 15:14

I agree that vdroop is a bit of a pain, in the BIOS i have mine set to 1.33V however CPU-Z reads it as 1.312V.

With regards to getting the stepping without the box, i am not sure, but i presume you can - help please

In CPU-Z, my cpu is labelled (from left to right):

6 F 6
6 F B2

as above, the stepping is only on the box and the IHS of the CPU, don't think there are any programs out there that can tell you the stepping....

466x7 @ 1.325v... 30 mins stable so far :eek:

V|per · 2 May 2007 at 16:45

ok, 475x7 @ 1.375v is stable for an hour of orthos (i cancelled it, didn't fail, will 24hour test it later) But if i up it to 476x7, it will just not post... have even thrown 1.6v at it just to make sure it wont go further.. is this common? literally hitting a wall in the fsb (i have tried every fsb from 475 to 525, just to make sure its not a 'dead zone')

CPU limitation or motherboard limitation you think? surely it can't be the memory? (set to 800mhz, have even knocked the timings down to 5-5-5-15-2T)

Mobo is the BFG 680i btw...

Cheers,

Hmm I seem to have run into a FSB wall as well with my 6300 and P5B-Deluxe. At 480mhz and 1.325v the system posts fine and passed Orthos for an hour before I cancelled it. However anything above 480mhz just won't post no matter how many volts I throw at the core.

I'm running the ram at 1:1 so I doubt thats the problem as it runs fine up to 500mhz on the same timings.

Edit: Also tried upping the FSB termination voltage and the northbridge voltage, and loosening the timings on the ram. Made no difference.

exactly the same here dude, have never used a cpu that stops just like this... crazy

Gatsby · 3 May 2007 at 00:10

Heh, to be honest 480 up from 266 is a pretty insane clock as it is, so I'm pretty happy

Would be nice to work out what exactly is causing the complete failure to post though.

Few things to try (in case you have'nt already):

1. Increase vdimm
2. Slacken memory timings
3. Increase NB volts

Whoops, just seen your edit, you've tried all those things. Ignore this then!
