hmm?? i think those chipset for socket 478 right?...my processor is LGA 775...thats why i use i915 for 775...if u see my cpu-z info..it said i use mpga 478...my cpu-z reading for the socket is invalid..i'll show u my processor and mobo

Hello there. I'm just a newbie in overclocking. can anybody help me with oc?

Original Socket = Intel Pentium 4 2.8Ghz C
Stepping = Northwood
FSB = 200
Clock Speed = 2800Mhz
Voltage = 1.6v
RAM type/timing = GSkill 512x2 Samsung TCCD/2.5-3-3-7

Motherboard
Brand = AsusTek Tech
Model = P4P800 Deluxe
Chipset = 865PE
AGP/PCI-E = AGP

Result
Highest FSB = 250.0*14
Highest RAM = 250.0 (1:1)
Highest Clock Speed = 3500Mhz
Highest vcore = 1.65v
Highest vdimm = 2.85v

Benchmark/Stability
CPU-Z validation = http://valid.x86-secret.com/show_oc?id=39057
Super Pi = 1M calculate : 40s
Sandra = 5262MB/s
3DMARK05 = 2178, http://service.futuremark.com/compare?3dm05=1234018
3DMARK03 = 4643, http://service.futuremark.com/compare?2k3=4267803
3DMARK01se = 14872, http://service.futuremark.com/compare?2k1=8724769

So, is there any way i can do to increase my oc? when i try to increase the FSB to 260, my pc will hang up and need to restart. All sifus here maybe can help me.

any1 tried overclock with p4 630 3.0 2mb with asus mobo??

nizamextreme !!!!!!!!!!!!!!
wat fan lai de?
led fan got 92mm de meh???
where u buy it????
i want led fan for my hyper48 too..

barclaycard07 , What's ur CPU batch?how many caps does it have, u can check by turning the cpu over facing the pins and count the number of capacitors there. Generally, a 30caps will give u good overclocks.

Bump the AGP voltage to 1.8v (max). This will increase the NB voltage. Set ur Vdimm to 2.75v

what fan?? thermaltake blue led...got it from low yat la dei..

sorry. my mistake but still...
sell the Intel board and get something from Asus/Abit.
You should be able to squeeze the every potential of the CPU

yeah...i'm looking forward to buy new mobo..maybe dfi..i read the review about this board...quite impressive for overclocking prescott...dfi lanparty ut 915 t-12..any suggestion?

Hey brothers, I want to overclock my p4 2.4, but I don't know what is the limit. Can anyone tell me how to determine the limit? Should I overclock until 3.0?

First state your processor. Isit a 2.4A or 2.4C? And also the associated hardware. If C which I presume is a Northwood, on air I can say that 3.2 is possible and prime stable. Even if one plays only with dividers. Best is you start off with dividers of say 4:5 if that option is available. Up slowly the FSB and test it with Prime@SP2004 (USing Small FFT in place test) which is good enough for a general stabillity test until you've hit the limit whereby there will be Prime errors after 5 minutes. Then test somemore by undergoing stress testing the last stable speed for at least 3-4 hours IMHO and if it's stable, you've got your limit. Intel processors generally don't require bumping up of VCore FYI

what do u mean by limit? u should try to overclock that 1st then you will know when u reach the limit

Hi all, want to ask something here
system spec:
P4 2.8GHz (northwood)
Asus 865P (800FSB)
1024 DDR400 kingston value RAM (4.3ns)
R9600P VGA

When I OC my system, anything more then 210MHz external clock (840FSB) and In 3DMark03 CPU test benchmark, artifect are everywhere.....only that benchmark, normal 3D benchmark, application all runs well. CPU stress test also didn't crash, running for few hours, CPU temp max about 50c, mobo temp max 45c

Anyone knows where the problem lies?

and also, will adding heat sink to that ram helps my overclocking?

thanks alot

Hornet, we'd need to know what those KVR's are using in terms of chips. If we don't we can't be sure. If Hynix then it'd be strange. If Elpedia or sumthing llike that...I won't be surprised.

Try using dividers instead to psuh up the proc if that option is available. And if I'm not mistaken, there's a prob with GFX's everytime you push up the FSB. Did you check whether the AGP frequency is properly locked at 66Mhz?

Hornet, which Asus 865PE ur using? If it's P4P800, there's issue on AGP tearing n artifacts. It's a known issue. Try these:

1) Update ur Mobo's Bios to the latest.
2) Increase Vagp to 1.6v

Erm, the RAM, KVR400X64C3A/512 .......Hynix chips BTW
The mobo, it's Asus P4P8X, northbridge supposely i865P (not PE though)
And yeah, AGP was lock at 66.66/33.33

Anyway, in normal 3D rendering, nothing wrong as far as i know...only that 3DMark03 CPU test, lots of artifect

Probably try increasing the Vagp to 1.6v?

Tried that, but unfortunetly it didnt work. The artifect still the same

hey i just wana ask a few questions...i hav a p4 2.4c northwood 533mhz fsb skt 478,msi neo2 i865pe,512mb ddr266 kvr and ati 9550 256mb.....now i oc-ed my cpu to 2700mhz which is stable,but when i try my fsb 180*18=3240mhz,it crashes...does dis mean dat 3200mhz is da max or something?btw my ram divider is 4:5 currently rucnning at ddr375 speed n my cpu multiplier is locked at 18x.wat should i do?change da divider,up da voltage or ?thx

kucingfight: Is there a reason you told barclaycard to bump vdimm to 2.75 instead of 2.85?

My own experience with my 2.4C hasn't been good, tried vagp up to 1.8 as well as increasing vcore up to 1.6, but it just won't be prime stable above 255MHz. I've already elimated the RAM by making it run at a lowly 200-220MHz and I know the RAM is prime stable up to above 255Mhz.

this is the common issue for 865 chipset when u use 1gb ram to oc

download this, change the dram latency parameter from 00 to 01
hope this help
