P4 2.8 Slz5 + Epox 4pca3+

**aristidis** · 12-20-2003, 02:02 AM

Just got a new 2.8 MO and an EPOX 4PCA3+ rev 2.0 and my first impressions are the following: with 1.65vcore i am stable at 265fsb and this chip looks that it can go higher. Post if tou can vcore settings and max fsb for 2.8 MO just for having some conclusions. And another thing, did any body Knows how match this Epox board undervolting?
And here is a first pic..

UNDERvolt?? I think your board is overvolting like crazy! If you set 1.65V in BIOS, and it reads 1.77V under load, it must be overvolting.

My .02

BTW: nice chip tou got there

The voltage reading in CPUZ is the AGP voltage and not the vcore.
If you sea the vcore voltage at USDM you are going to understand what i mean. With this chip i was able to post at 287fsb with 1.8vcore but of course it is not stable at all. I want to burn in with Prime for several hours and going to higher fsb's slowly hoping to get much better resaults.

That looks to be a good chip you have their

My 2.8C non MO would only hit 3.5Ghz on water. So I'd say you got a good one

How is that GEIL PC 42OO working out ??

**Shane5578** · 12-20-2003, 07:34 AM

i'm starting to see alot of happy epox users. lol

I only can saw you a Sandra Score with an 2.6C on my old MAX3
300fsb with timings 7-4-4-2.5 They are grate to me...

Antil now it looks a nice board, but i want to sea what that chip can do on the MAX3 that arrives from day to day, beqause my old one is dead and gone for RMA.

**Grace** · 12-20-2003, 11:50 AM

The Vcore on the Epox 4PCA3+ is rock stable within 0.03v from where you've set it at, idle and under load. Forget what the Winbond monitor tells you.

i want to sea what that chip can do on the MAX3 that arrives from day to day, beqause my old one is dead and gone for RMA.

You'll get about 100-150MHz higher at the exact same settings.

**Shane5578** · 12-20-2003, 12:52 PM

my mum is called grace too. lol

it will be interesting to compare epox and abit.

Those programs to read voltages are useless... the only way to really measure voltage is with a voltmeter.

Measuring real voltage, the 4PC3A v2.0 undervolts about .025 so your 1.65 is really 1.625

For me, using all the same components my MAX 3 maxed out at 270mhz FSB 5:4 , my Epox gets up to 288 FSB 5:4 .

I hope that Grace, until now i am prime stable 275fsb with 1.725vcore and going up.

With my 2.6 L321 Max3 was better and more stable at high Fsb's.
Let's sea what will happens with this chip.

Yeah aristidis right, mine also read the voltage wrong in cpu-z. It's reading the voltage of from my vagp instead of the vcore.

The vcore to this board undervolt to about .025-.05 in my board, but the vdimm and temp is pretty much on the money.

**aristidis** · 12-21-2003, 01:49 AM

Yes this board undervolts at vcore and in mine it's about 0.05, but the most important is that vcore it isn't stabe in full load.
And a new pic of 276fsb

**TASOS** · 12-21-2003, 03:49 AM

Overclockability & Epox ?

xxmm...it's just us Grace told you. 100-150mhz less than a Asus or Abit.

I have tested both the Canterwood and Springdale Epox mobos.

**retrospooty** · 12-21-2003, 09:29 AM

I just used the Epox "magic BIOS" utility and got the 12/16 BIOS. I was able to eek out a few more mhz with it.

It has some new memory tweaks as well.

I can't find the new bios anywhere on there site. Do I have to use the flashing utility that came with the board to update to the new bios?

Yep you have to use the magic bios utilitie. Just flash it but dont test it yet.

**aristidis** · 12-22-2003, 10:53 AM

I also have noticed that the mofsets of that board are extremely hot and after placing some ram heatsinks and an 80mm fun on them i was able to run at the same clocks but with less 0.025 vcore and more stable ..

**~~NaHeMiA~~** · 12-22-2003, 03:47 PM

VEry nice overclock

Would like to test a chip like that under my prom mk2

I cannot use the Magic Bios Utility yet, due to the fact that I just move to a new home and haven't hook up the phone line yet(going through the process). I can download the bios from here(at work), but I cannot install the magic utility onto my work computer(it not an epox machine). So, can anyone post a link or something that would lead me to the new bios. I'm so anxious to test out this new bios. Thanks in a million.

**Alexandrus** · 12-23-2003, 12:03 PM

Yeap, I want the new BIOS asa well, but no mention of it on EPoX's site.

**retrospooty** · 12-23-2003, 05:04 PM

There is a post in this thread with a link.

I'd try that zip file from leotonch, and it's telling me that the bin file is not an award bios. Lemme try it again and see what sup.

**aristidis** · 12-24-2003, 01:19 AM

New bios tested, but for me isn't better than the old one, 2-3 lower fsb for stable settings. And this new memmory setting it's better to keep it Disable..And....MERY CHRISTMAS TO EVERYONE

**Alexandrus** · 12-24-2003, 03:18 AM

I'll try it today and let you guys know how it works.
