Re: GA-EP43-D3SL + E8400 - 4GHz?

it should,change the MCH latch to 400,bump CPU termination to 1.32, reference 64% from Vtermination, mch core 1.24. and just for your knowledge, i've learned that from a very smart man, those boards have HUGE Vdrop, so anything u put on bios , is actually 0.4-0.6 less, try bumping to 1.4-1.425. if it wont post, u need to change the timings for 5-5-5-18, and about advanced timings ask "lsdmeasap".

EDIT:

CPU Thermal Monitor 2(TM2) ...........: [Disabled] WTFFFFFFFFFF DUDEEEEEEEEEEEEEEEEE ENABLE IT FASTTTTTTTT

I've just tried all of that, and it would still not post.

Don't exaggerate, as long as you keep your temps cool (and your eye on it

), there's no real need for this feature.

@lsdmeasap: Save me?

if u set timings and everything on auto, will it post?not cores, only timings.

Re: GA-EP43-D3SL + E8400 - 4GHz?

how much memory do you have? 2x1GB, 2x2GB or 4x1GB? try these settings for 4GHz... i've listed timings and voltages for both 2 and 4GB memory... 4GB is generally looser...

the droop on the P4x boards is pretty massive, so start the voltage in the core high and work down if you cant boot. for all the timings i've listed a range for, start with them loose and tighten them up one at a time if you're able to boot, testing with MemTest86+ (Memtest86+ - Advanced Memory Diagnostic Tool) between each move

**MiOB** · 10-13-2008, 10:56 AM

Re: GA-EP43-D3SL + E8400 - 4GHz?

@BongWizard:

It's 2X2GB. I'll try your settings and will report back!

**Lsdmeasap** · 10-13-2008, 11:04 AM

Re: GA-EP43-D3SL + E8400 - 4GHz?

Right, please post a link to your exact ram so we may better advise you. I can say Auto is not going to be much help to you.

The voltage you have, as suggested above, is really only 1.3 or less in in windows. So you will need to increase that for sure. And depending on your ram you will need various other changes, no matter what AUTO has got to go on alot of those

CPU Thermal Monitor 2(TM2) << Should ALWAYS Be enabled, so your PC can shut down should your fan die when you are not looking

Post your ram link, and if BongWizards settings do not get you going I will post some settings for you. Please also post your intended CPU Speed

**MiOB** · 10-13-2008, 11:27 AM

Re: GA-EP43-D3SL + E8400 - 4GHz?

Well, I've just tried BongWizard's settings - no luck there.

@Lsdmeasap:

My ram is G.Skill's F2-8000CL5-2GBPI X 2 (2X2GB), rated at 1000MHz 5-5-5-15 2.1v.
A link to G.Skill website: DDR2

I enabled CPU Thermal Monitor 2(TM2), by your advice.

As for voltages, I've tried both Auto or Manual - very high voltages.

Do you think you'll be able to help me reach 4.00GHz?

**Lsdmeasap** · 10-13-2008, 12:39 PM

Re: GA-EP43-D3SL + E8400 - 4GHz?

Yes, you can do 4Ghz for sure. You just need to get your ram going first and then you will be fine.

Here, try this for 4Ghz. And keep at it, dont give up after a few tries it does take some time. >>>>

Re: GA-EP43-D3SL + E8400 - 4GHz?

Sorry,

I did try to update each one at a time and reboot and update again, but... it just didn't work. Everything worked, up until the last stage, where I turned up the FSB, even if just from 419 to 420. 419 boots, 420 doesn't; nor 450.

Do you believe an BIOS upgrade would help here?

**Dymblos** · 10-14-2008, 01:45 AM

Re: GA-EP43-D3SL + E8400 - 4GHz?

X_x.. u have F4 bios.. pls update to F8 or F9 if u r using win vista

**Lsdmeasap** · 10-14-2008, 02:41 AM

Re: GA-EP43-D3SL + E8400 - 4GHz?

Yes, it likely would since you are using such a old BIOS version. Please read here before you flash, and DO NOT USE @BIOS >>>

http://forums.tweaktown.com/f69/bios-flashing-how-qflash-guide-27576/

You did pick the Budget P43, + Budget Model "L" so you may be at the top end of the double budget board though, just not sure. But yes I would for sure flash to at least F7

**MiOB** · 10-14-2008, 12:40 PM

Re: GA-EP43-D3SL + E8400 - 4GHz?

I read through that topic, but I haven't a floppy drive; can I flash using a bootable CD?

**Lsdmeasap** · 10-14-2008, 01:05 PM

Re: GA-EP43-D3SL + E8400 - 4GHz?

There is info there on how to do it from USB, do you have one of those?

You do not need anything "Bootable" you can go right to qflash from the BIOS or the Post screen, using the "END" key at boot time, or while on the main page of the BIOS hit F8. Then all you will need is to have the BIOS .Fxx File on a USB or FAT32 Partition. Leave the USB Stick in when you reboot to Qflash (Just meaning you cannot plug it in while you are already in Qflash it wont be recognized)

But to directly answer you, yes you can flash from a bootable CD. You would need to boot to DOS from this CD, and then put all 3 BIOS files onto another CD insert it and flashing by running the batch file, or the Flashspi/flash895 command with the name of the BIOS file following the command

It would be much easier for you to flash from Qflash though, with a USB Stick

**MiOB** · 10-14-2008, 01:12 PM

Re: GA-EP43-D3SL + E8400 - 4GHz?

Yeah, I'm sure it would, though I haven't one.

As for the CD flashing, why would I need two CDs?

AND - Do you happen to have a boot image that I could burn?

Thanks lad, you're very helpful!
