Trying to reach 3.8GHz

[systemlord]

I am currently at 3.6GHz 1.56 Vcore and need some suggestions on how to best reach 3.8GHz. My FSB @1600MHz with Ram @1200MHz @2.25v & FSBRAM 2:3. I dont think these Asus P5B's can run unlinked. Thanks for any suggestions!

increase your multiplier. Splash it with water if it smokes

 

[SuperFly03]

Ram @1200MHz @2.25v & FSBRAM 2:3.

No wonder you are having issues. :roll:

 

[derek2006]

Your C2D is not gonna last long at that voltage. Your PSU may be holding you back. Also like superfly said your ram probably is maxed out.

I did try spashing water on my mobo and it help a little,lol. I am using FSB @450x8 multi, Ram @900MHz @2.25 & bus speed @1800MHz 69% OC on bus. Vcore is being lowered as I speak & for now seems stable, but I'll keep lowering it till I get instability. My temps are pretty good 62c Tjuntion both cores Tcase 50c which is under 12c max thermal temp of 61c for C2D's

Your ram can't run that fast. That is well past the world record. You are mistaken it must be running 3:2. Which is only DDR2 600. If you somehow miraculously reached what you said you did take screenies now and buy new ram modules because their not gonna last much longer.

CPU clock 3.6GHz, Ram @900MHz, bus speed 450MHzx8 multiplier x4 = Rated FSB 1800MHz, why is that so hard to understand? Do some math. If you tell me how to put CPU-Z in here I'll show you.

 

[derek2006]

O LOL ya my bad. I was thinking that it was running at 900mhz and the effective speed was 1800mhz. Sorry for any trouble.

Nice OC by the way. Try to get your voltage to below 1.55 because that is the absolute max voltage for C2D's if you want them to last till at least their 3 year warranty.

I am in the process of lowering it as we type, now its at 1.53 Vcore. Temps are 63c Tjunction both cores, Tcase 50c.

Load up multiple CPUZ tags, core temp and Ortho’s priority one for 2 hours and post your screen shot like this.
Priority one is so you can still use the computer.
Priority 9 if you dont need the computer for anything




Make sure you don’t post Ortho’s when it’s at Idle.
You need to make sure you’re absolutely stable at 400 FSB before you go past that strap.
It would be refreshing to see 1200 MHz ram on the P5B Deluxe as there are not very many people that can manage this especially at 2.25 Volts
If you can post 500 FSB then you probably don’t need any help other than a few pointers

 

[bkiserx7]

have you tried 475 with an 8 multi?

I just finished 3 hours of Orthos blend priority 8 @3.6GHz Vcore 1.50, 450x8 multi, Ram @900MHz 2.25v and I know if I raise the Vcore some more I can run with no errors. I already ran Orthos priority 8 for 14 hours at 400x9 @3.6GHz Vcore @1.55, Ram @1200MHz 5-5-5-15 @2.25v STABLE. I think my CPU is wanting more voltage than I'm willing to give it, as if I drop below 1.55 it gives me errors in Orthos. One more question, is it better to run @3.6GHz and Ram 2:3 ratio @1200MHz 5-5-5-15 or running @3.6GHz with ram @1:1 900MHz? "Tell me how to take a snap shot of all those programs and how to insert them here. Then you'll see 1200MHz @2.25

its better to run the FSB ar 400 X9 3.6 GHz 4:5 DDR2 1000
or 467 X 8 for your maximum bandwidth.
at 450 FSB the bandwidth drops.
I would really like to see that 1200 MHZ orthos stable screenshot and I believe you would have a world record at 14 hours stable at 2.25 volts providing it was a blend test.
use Asus Ai suite to show ram voltages on your screenshot.
and dont give up those ram modules
unless you want to give them to me

 

[systemlord]

Yes I did try 475x8 multi but the computer kept hanging(black screen non responsive) on me, you know why? I upped the FSB volts & NB volts as well, I'm I doing something wrong?

Can you explain to me why 400x9 or 467x8 is better than 450x8? Not that I'm questioning you I just crave knowledge when it comes to computers. Also if you could tell me which would be better performance wise between 400x9 vs 467x8 as I think I can manage both. One more thing is that @400x9 I am unable to go any lower than 1.55 Vcore and if I do it hangs(black screen non responsive) O yeah at 400x9 my temps are using TAT at 85% load both cores is 65c-66c Tjunction as Tcase is not trustworthy. And thanks for you help mate!

 

[derek2006]

Ha I found it after much searching. I use to have this bookmarked in times like this but it disappeared. Very good explanation as to why it's better.

I think I only understood less than half of the P5B stuff, strap what the heck is strap? I'm a noob OCer and that was just fracking over my head> :? So do you think that 400x9 @3.6 GHz Vcore 1.55v with temps using TAT at 64c-66c loaded at 85% load is ok to run? I heard gaming will NEVER reach those temps, is that true also? Thanks for trying to help with that link even though....

 

[derek2006]

Ya it's pretty confusing I read it 3-4 times before I got it.

Whenever the fsb hits the strap the chipset reduces it's own multiplier and therefor reduces it's internal clockspeed allowing the FSB to scale even higher and giving you a higher OC. When it reduces it's clock speed the bandwidth decreases. Thats why you want your FSB to be right on the strap so it doesn't reduce it's internal clock. Sometime the chipsets won't be able to hit those clocks thats why some people experience problems where they cant go higher. They have hit dead zones where you can't increase your FSB anymore from like 380-400. But after your pass the 400mhz strap and the chipset reduces it's internal clock they are able to increase the FSB clock even higher. Thats my understanding of it all.

Your temps are all fine. Your in the warm zone, hot is 75C+ and throttling starts at 85C. However if you want your chip to last till about or past its 3 year warranty you will need to reduce the voltage.

So if I deside to lower my OC to save my CPU from voltage death, what would be the next best setting, 333?

 

[derek2006]

I would run that CPU at 3.4 GHZ. You could most likely get a decent voltage and life span at that. It doesn't really matter if you use 378*8 or 425*9 because they almost have the same bandwidth.

The first thing you want to do is pull that ASUS sticker off the Northbridge and stick a fan on it.

Try 400X8 3.2 GHz and set the ram to 1000 MHz in bios at 2.2 volts
In the chipset section of bios under Northbridge chipset configuration
Click disable Configure DRAM timing by SPD
Set the Ram Latency at 5:5:5:15
CPU Vcore 1.45
FSB termination 1.4
NB 1.45 increase to 1.5 if Orthos starts to fail (before you increase Vcore)
Do not raise the NB Vcore to 1.65 (your not ready this yet)
SB Auto
ICH Auto
Run Orthos at least Priority 7 for no less than 5 hours and if your temps are less than 63 (core temp) and less than 61C Tcase (Asus PC probe)
Run Orthos overnight.
Drop your Memory back down to 800 MHz at factory rated Latency if Orthos fails
Raise your Vcore only if NB volts and Ram Frequency doesn’t correct failures
After your stable you can start to tighten up the memory timings and recheck in Orthos and Memtest.

I know this is of topic but can I install the sata drivers (AHCI) after OS install? If not then do I need a floppy or flash drive?

 

[kwalker]

You need to install AHCI or RAID drivers before OS install Make a floppy before you reformat If you deside to do this.
I'm not a raid expert if you run into problems
I can make it work but struggle when it fails :lol:

 

[systemlord]

USB flash drive wont work?
