GA-EP43-DS3 Overclocking advice

Re: GA-EP43-DS3 Overclocking advice

Nah, not here. On another forum, just got made out like it was a stupid question and I shouldn't bother learning about any of the associated bits and pieces.
Does it make any difference to how far I can clock the cpu? Other than the dates and batch number what can I get from those details?

Re: GA-EP43-DS3 Overclocking advice

The batch just can help you kinda guess what the CPU may or may not do by googling the batch number is all. Or part of the batch # like 3850A and leave off the rest.

How far you can clock it depends on your cooling and how much volts you will put into the cpu, and of course the CPU itself and you board. P43 is not as good as P45 or P35, so keep that in mind when you are looking through results in google

Re: GA-EP43-DS3 Overclocking advice

One problem however...whenever I put the computer to 'sleep' and then 'wake' it the computer doesn't POST and cycles through power on/power off. As it works OK the rest of the time this is a bit annoying, any suggestions?

BIOS F9 lists

F9 2008/09/22 1. Fixed Vista S3 resume sometimes failed

Re: GA-EP43-DS3 Overclocking advice

I've flashed to F9 BIOS already. Read somewhere that it might have something to do with S3 (a.k.a. Suspend-To-RAM or STR) to S1 (regular Standby). Any ideas? I'm at work but will try change that option when I get home.

Re: GA-EP43-DS3 Overclocking advice

S3 resume from sleep will not work until your system is 100% Fully stable, with your own manual settings.

Please give me your full settings you are using now and I will advise back, template in my signature for BIOS settings.

Re: GA-EP43-DS3 Overclocking advice

Ohh! Well there is the problem right there, you can't just run a overclock on Auto for a few reasons. It wont always (Generally) be stable, and you can kill your CPU like that.

That's not a huge overclock so I wouldn't worry about having hurt your CPU but you need to set things manually, and you will have to test and tweak until things are 100% stable with Prime95/Orthos and Memtest86+ before S3 is going to work for you

Please read the guide for overclocking, I know it is not for P45, but it will give you some general tweaking and testing knowledge so you can try to get stable.

Here is some setting ranges to work with

Re: GA-EP43-DS3 Overclocking advice

Spec sheet shows 127.5ns for tRFC, that's 68 for DDR-1066.

Re: GA-EP43-DS3 Overclocking advice

Spec sheet shows 127.5ns for tRFC, that's 68 for DDR-1066.

Do I have to use the values off the spec sheet or are they variable?

Where can I get the spec sheet?

Please bear with me if some of these questions are a bit basic, I'm keen to learn but a bit new to this :o)

Thank you!

Re: GA-EP43-DS3 Overclocking advice

The spec values are "safe", lower values might work but need to be tested throughly, sometimes higher values may be required.

Where can I get the spec sheet?

The PDF link in your first post.
Other timings that do not show in the PDF you can see with MemSet's spd (cycles for specific speeds) or with SPDTool (time), both can be found in the programs sticky.

The PDF link in your first post.

Ohh 8-) *feels incredibly stupid*. Thanks, I'll go download and print it now. Having some MAJOR irritation with BT at the moment. Overnight they have decided they can't supply my house with broadband as we're too far from the exchange...even though they've supplied us since March '05. Either the earth
has expanded or I now have the amazing talent of being able to move my house.

Anyway, rant over :o) feel much better now. Virgin Media here we come...

Re: GA-EP43-DS3 Overclocking advice

So how you coming along with things? Just checking in

[nav_kundra]

Re: GA-EP43-DS3 Overclocking advice

Hi there!

Sorry for not getting back to you sooner, can only access the internet at work as BT still can't sort out the access at my home.
I got on okay, applied the tighter timings from the range you suggested last time around and booted successfully. Was stable for the whole test period of an hour and a half but still wouldn't cope with S3 sleep. I knocked the FSB back to 333MHz and upped the multiplier to 9x, matching the memory latch at 333MHz and fixed the speed with the memory multiplier to 1066MHz too. This was also stable and did suspend to RAM (S3). Only gives me 3.00GHz which isn't very significant. When I put the multiplier up to 10x I can't get past the Windows boot screen, on either Vista or Windows 7. Don't know what to change first to try get a little further?

Thanks :o)
