Hi everyone,

I'm al little new with oc but I do my best. I can't get my FSB higher then 215

Here are the specs I have:
Thermaltake butterfly 480W psu
Asus P4C800 deluxe (bios 1019.002)
Intel P4 3.4 (northwood) with Zalman 7000A-Cu
2x512MB OCZ DDR PC-4200 / 533mhz / Performance Series
2x80GB (stripe)
2xDVD
pci Creative audigy 2
pci Gigabit lan
pci ISDN card

With these specs I cant get my system higher then FSB 215 and CPU 3.66 Temps are below 45 celcius.

Here are the settings from my mobo:

CPU External frequency: 215
DRAM frequency: 400
AGP/PCI: 66.66/33.33
CPU Vcore: 1.6000v
DDR: 2.75v
AGP: 1.60v
Performancemode: standard

Config DRAM by SPD: Enabled
Spread spectrum: disabled
MPS: 1.4

When I use FSB 220 my system will start but crashes after 5 minutes playing games.
When my FSB is 225 my system starts but windows crashes at startup. FBS is 230 my system won't start at al.

I think it is possible to get better performance with these specs. Help would very nice!

Cheers!

check how much the vcore is drooping under load, you might need to do the droop mod.

oh and welcome to the forums

[Time4aMassiveOC]

i have my spread spectrum enabled as default anyone know what that does?

[ukdan]

Not quite sure but i heared that it can effect overclocking so i disabled mine.

Just because you have some decent componets it doesn't mean they will OC with ease.

Your memory settings might be holding you back. In your bios disable "config DRAM by SPD" Find out what your memory timings are from the manufacturers web page, expample--2-3-3-6. Losen your timings a bit for instance to, 2.5-3-3-6.

Thanks for the welcome Ukdan. What is the "droop mod"??? LOL...Never heard of it. Or can you explain it with other words.

Cheers!

Before you go modding your Mobo, try Rangers advice and set your Cas to 2.5

It works wonders. I was running into the exact same problem on my ASUS Board.

Thanks, I think I already tried that by putting them to the highest (slowest) settings. But I'll try again.

To bad...I changed the SPD settings to manual, but System crashes after 1 minuut in Windows

Cas=3.0 (2-3)
Ras Precharge 4 (4-2)
Ras to Cas 4 (4-2)
Precharge delay (8 (8-5)
Burst length 4 (4-8)

Anyone other suggestions?

Cheers!

Before you go changing you spd latencies you have to find out your memories default timings. I'd suggest going to the manufactuer of your rams website and look there. then once you know the default timings, set them, restart and then losen them a bit i.e. 2-2.5,- 3-4,-3-4,-6-7. Post back with your default timings and we can tell you what settings to try.

Hi Ranger,

This is what I found on the website:

OCZ DDR PC-4200 / 533mhz / Performance Series /Dual Channel
OCZ Performance Series PC-4200 memory is specifically designed for high frequency operation on Intel i865 and i875 chipset based motherboards through OCZ’s HyperSpeed® technology. It is capable of reaching outrageous speeds of up to 533MHz at CL 3-4-4-8. Because these modules contain special PCB’s and firmware to allow the module to run at the highest possible frequencies, timings lower than CL 3-4-4-8 may not be possible, regardless of the module frequency.

Every Dual Channel Kit from OCZ is hand tested as a matched pair across a wide variety of motherboards to ensure flawless performance on most motherboards.

Additionally, OCZ PC-4200 Performance Series memory features OCZ EVP® Extended Voltage Protection, a feature allowing performance enthusiasts to tweak their systems up to a VDIMM of 2.9V ± 5% without invalidating their OCZ Lifetime Warranty!


What settings do I have to use?

Cheers!

ps: Merry Chistmas to all of you!

Ok, drop your CAS to 3.5(I assumed you were running standard DDR, instead of DDR2)

THAT should give you a little bit more headroom...

And the droop mod basically gives you a little bit more power on your mobo, for better OCing.

I can't set CAS tot 3.5. I can only choose 2- 2.5- 3

Cheers!

guys should he set 5:4 ratio (320) just to eliminate the ram and to see how much he could push the cpu?
then work on ram after. worked for me.

[Sjaak]

His RAM is ddr4200....that shouldnt be a problem up to 263 FSB (on stock / loose timings)

As said before somewhere, check your PSU lines. Do they drop much under load? 1.6v may be too low for 3.66Ghz, try upping it to 1.625 or 1.65. Are you sure the AGP speeds you stated (33 / 66) are FIXED and not MANUAL?




(looking at your username, i assume you are dutch, like me. If you want some help in het nederlands, voeg me dan toe op msn / mail ff (zie profiel))

I see what your saying but i have the same ram and i remember having the same problems. The ram wouldnt do its rated speed at the timings specified by ocz so i eliminated the ram by setting it at 5:4 ratio, found the max my cpu could do then had a play with ram settings.

[Elif Tymes]

Yes, he can do that for now, its not a "fix" per se.

Quick, what Bios Revision are you running?(As no CAS past 3 just seems.. odd.. to me)

[heineken01]

Thanks Guys for the help.

The bios version is the latest from the asus website: 1019

I have tried to find the 5:4 ratio in the bios but where is it??? Can't find it.

Cheers!

[ukdan]

set DRAM frequency: 320 that'll give you 5:4 ratio
