2.4c @ 3.82 - default voltage 1.525

[r00t3d]

Where do I start

I am seriously impressed with the chip I have, I have got it to 3.82GHz @ default voltage of 1.525.



With all this glory comes some sad news, for which there is most likely a FIX

Windows XP just takes forever to bootup, everything runs dog s**t slow, this is anything past FSB of 300, then I get this, my system Windows XP, keeps coming up with an error "Windows has recovered from a device failure" you need to save work and reboot yada yada yada... my system then goes into 640*480 and I cant get it into a higher rez, I somehow have the feeling that the graphics is letting me down here.

I currently have the radeon set to 1.7v from the bios, It can go higer upto 2.2v, do I need to RAISE the voltage on the graphics?
or do I have a driver problem?

I am lost, any help appreciated.

[r00t3d]

By the way, once I get that error message from windows, everything works fine again, and safe mode has no problems, seems like a graphics/driver problem

[sandman]

Sounds like it might need more voltage, or maybe the northbridge needs more voltage.

[r00t3d]

Then again maybe the northbridge needs better cooling, currently its on the standard HS that comes with the Epox, I havent even put any AS3 on it.

id be seriously impressed with an oc like that m8... good job and on stock...wow...

if u dont mind telling me wots ur specs of the machine ur running it on...im using a 2.4c cpu as well but have major probs getting stable at 3ghz...hopefully its cos of the ram thats holding me back...current one i have is a week 11 malay which si supposedly good for 3.6 on air.....btw im using an abit ic7g with 512mb ocz el gold pc3700 sticks...

again nice job done m8...

oopps as regards to ur problems in winxp...wot drivers are u using for the radeon gfx??..latest cats??...if so try the older ones etc...u coudl try upping ur agp voltage..might stabilise it a bit or up ur vcore a tad as well....and vdimm if u can....other than that it could be a northbridge problem...but hard to say...

[SpicyHuevos]

try a different video card. and what psu you using.
I had same issues with my 9800 at 4200 with a 2.8p4.
I got a differnt ati and it stopped

[j2me_tech]

the speed is achieve using prommy or air cooling? prommy i suppose . nice btw .

[charlie]

do you have winxp sp1?

Hey nice OC

I have a 2.4C sitting here not opened and was wondering what Week and place of make yours is?

Cheers

Set AGP/PCI above 66/33. Should fix the 'slowdown' problems. Use setfsb to check the AGP/PCI speed. It can also be used for adjusting AGP/PCI too thou.

Nice r00t3d !!!!

how about some details about the chip ? stepping ?

[r00t3d]

Sorry guys,

I went to bed after all that last night, just got up

I am/have been using 3343 drivers and 3307 drivers. (didnt work either unless this device failed and everything went to 640*480)
PSU: Antec True Power 480watts

charlie: I am using WinXP SP1

j2me_tech: yes its prommie cooled

macci: AGP/PCI is set to 66/33 what is a stable option?


Stepping Info etc: (this is what CPU-Z tells me)

Cpu Name: Intel Pentium 4 (Northwood)
Specification: Intel(R) Pentium(R) 4 CPU 2.40GHz
Family / Model / Stepping: F 2 9
Extended Family / Model: 0 0
Brand ID: 9
Package: mPGA-478
Core Stepping: D1
Technology: 0.13µ
Supported Instructions Sets: MMX, SSE, SSE2

Nice one

But can u read the FPO/BATCH from the box pls?

Cheers

[r00t3d]

I forgot about that

MM#: 852314
FPO#: L311A878

Thanks for that r00t3d

So its a Malaysia Week 11 huh.....very very very nice cpu

Wonder if my Costa Rica Week 20 will do anything like this
heheheh

[r00t3d]

Tried pumping the AGP to 75MHz, still no luck.

Heres something interesting though.

I deleted the Radeon 9800 Pro, from the device manager, when the system restarted, it was all ok, but obviously in a low rez, system booted up, then.... XP found new hardware VGA Controller, and then booooom.... the system went balls up again...

Should I try removing the ATi drivers first and then removing the Radeon 9800 Pro from the device manager? and see if windows will use its own defaults?

Gimme some clues, someone must have bumped into this

[Morkai]

I had a same problem and AGP trick worked very well. I boot to Windows 300MHz and raise AGP frequency to 72Mhz and FSB to 309MHz.

interesting my 2.4C is close to yours

SL6WF | Costa Rica | 3312A396 | 05/12/2003

about a week difference

Yours is Cost Rica, the one I have is Malaysian, big difference as a lot of people will tell you.

[bcn]

they say costa rica is also good... - who knows...
I have the first one from costa - always was gettin' malaysian ones.
I have 3318A264-1028 pack date 06/06/03
and it does 3GHz on air at 33C+ ambient temp and 1.6V - not really something outstanding.

Holy smokes thats sweet at dflt volts

Slow but booting and working has always been nb for me. If I OC my cpu too high, system crashes. When I'm testing a fsb increase, video openings to cames and such will run all slow. I"m an AMD guy so who knows. That also means that with multi adjustments, I was always able to narrow it down to this when this garbage happens to me. Well you know with more volts you should have more MHz room so if upping the voltage does not help your situation, you'd figure all finger point to mem/nb.

[althes]

That is a sweet oc. Hope you get the 9800 working.

Also when u say Default voltage, do you mean its at the setting of 'Default' in the bios?

Or you have put at a higher volt in bios so that when it undervolts it hits 1.525?

Cos when I say default volts, I mean the top option, and thus the real vcore is actually about 1.44vcore load
hehehehehe

[r00t3d]

In the bios I can go upto 1.6 volts, the CPU is set @ 1.525 which is the default setting +/- 0, increments of 0.025, that reminds me, I can also lower the voltage.

Here is some more news, I put a dual boot onto my system yesterday, Windows 2000 SP3, where I wasnt stable above 300, in XP, I am now stable @ 309 in 2000.

I know where my problem lies, its the cooling for the NB and GPU once this is fixed (very soon) I am going to UNLEASH the power of this 2.4c.

Does anyone know what the highest o/c has been on a 2.4c? is it macci @ 3.864 ?

[macci]

Its a bit more than 3864MHz

MAX WCPUID (Vcore 1.65):


MAX SuperPi 1M (Vcore 1.65):
4220MHz

MAX SuperPi 8M (Vcore 1.65):
4188MHz

All limited by motherboard (Albatron PX865PE Pro with supercooled NB)
