I've never seen a chip running ~stock vcore up to 800mhz OC then require a full .30 for an xtra 50mhz. the heat also rises exponentially like I never seen before. Leakage of AMD's 90nm chips is talked about extensivly at overclcokers.com by ed. Leakage in general, for all chips, is all over the net and it's a natual phenomina but worse with 90nm afaikt.

-Try 2720 and see how much Vcore is required to keep stable, if the heat does'nt crash it first. Limit? sure, but this immediate all-of-a-sudden limit I've never seen b4.

I see it makes sense, but I just didn't see it with mine at 2650mhz....I have actually got 2.7ghz steady at 1.62v....

So from 2600mhz to 2700mhz or 11fsb it did take .15v more...nothing surpirising as it seems that this chip is tapped out...

I imagine that 2720 wouldn't be stable with 1.62 but I am not willing to go any higher on air....

Yes I have some cheap buffalo 2x512 cas 3 and some Crucial PC2100 2x512

What I'm going to do is not like above sandra and crap sythetics but real world tests...games etc.


with about 5 different situations all at same chip speed.

Somthing on the order

Expensive rams:
290 1:1
200-215 2-2-2


Cheap rams:
290 using a 133 mem setting making 192Mhz which any PC3200 can handle 3-3-3
290 using a 100 mem setting making 145Mhz which any PC2100 can handle


I'm open to ideas as I'm still formulating the test... there are literally millions of pumutations and I'd like to only do 5 or 6 tests... only to differentiate budget ram from ram that costs twice as much...


Anandtech and every other reveiwer as far as I'm concerned, is doing a diservice by constantly reviewing only overpriced ram in thier reviews...we shall see🙂
 
That would be intresting to know . do you have any auto cad programs my 754 seems to hangup when i load programs from home .
and my mem will drop from 340 to 91 mb setting up the jobs for the CNC mch . games dont seem to take that kind of hit in mem .
that would be real world for me .
 
I find this interesting considering people are going faster with .13's. Maybe a little work will help it out. I remember people complaining about the poor OC's on early 754's back when they were out a month or 2.

anyways im buying this board, If it sucks i blame Zebo 😉

HA Couple Issues for those willing

1) ram slots 1 and 2 basically don't work mem test fails even stock. Use 3 and 4 if dualling
2) mobo volatges are waaaaay off in software like speed fan/sanda. Ignore.
3) NBHSF is active which means noise. I cut up my A64 retail HSF and glued it on to make it passive. No noise. Zalman makes a $6 passive NBHS sold at any fine etailer if destruction of property is not your thing.

Other than that it rocks

Almost, now you can get into 939 for ~$250 vs $202 for 754


I still think 754 is a better deal price/performance, ignoring features.

I'm trying to build a great value system and your results on the 3000+ are making me think it's possible to drop down to the 3000+ and save some money to go elsewhere & still get similar results as O/C'ed 3200's. I've been wondering about the push towards crazy priced RAMs and any input on what kind of value based RAM would give good results, even if not the absolute best if it means more money in my pocket.

Well I'm on water so be careful my results may not be indicative of future perfomance. Although duvie hit 2600 no problem with stock HSF....

Is there a particular stepping you guys are looking for? These are astronomical numbers.

I'm assuming the price of the Epox board will take a $10-$15 drop within a month or two. The "budget" versions of their boards always seem to do that. I think I'd rather get that board and a winchester, than the DFI/Epox s754 board and a 2800+...although that DFI board is very, very nice. I just have more trust in the winchester for OC'ing than I do the 2800+. Decisions, decisions.
 
I'm probably going to upgrade my system by next February and I've been debating 939 vs 754 for awhile...was more set on 754 until I see a lot cheaper boards coming out for 939..hrm....
 
Zebo-that test has my interest picqued. Should be sweet since I have Corsair VSPC3200 and a 3000 Winnie. Don't get my AV8 until X-Mas, though. I could possibly collaborate with you if you're still working on it by then-just tag my results onto yours for a broader focus. LMK.

 
This board sucks with ram 1T or it does'nt liek TCCD.

First slots 1 and 2 bascially don't even work.

In slots 3 and 4 I can do 2-2-2 1T up to 215Mhz then we start having problems.

2-3-2 1T only good for 225 (anand got 218 in MSI with same ram)
3-3-3 1T only good for 230 (anand got 240 in MSI with same ram)
3-4-3 1T only good for 237 (anand got 267 in MSI with same ram)

After that it's all 2T which is a big hit on performance. You can even feel it opening and closing programs etc.

I can run 295 1:1 2t 3-4-4 but it's slow (same as DDR2)

So my advice is don't get TCCD expecting high bandwitdh and 1T. Either get cheap ram and use divider or some LL ram and use a bigger divder.

 
Another problem with this board I discovered last night is it has no 12 or 3.3 voltage monitoring. Seems all epox 939 have this problem from what guys who own them tell me. AFIAK I'm the first to have J board, but it's basically identical to the $130 + board and the problem obviously has'nt been addresseed...

If you like to look at PSU voltages inside speedfan or sanda stay away..
 
Slowly but surely I'm sinking back to DFI, 3000+ or 3200+, and some unnamed value RAM.... hopefully I can clock to 2.5 despite the non-TCCD 2-2-2 ram.

Seems to be that way with all A64 Epox boards. My mother's 8KDA3J board has no 12v or 5v monitoring. Speedfan scared me at first until I realized what was going on. Hmm, that's not cool.
 
who cares if it doesn't have voltage monitoring really, its still a "winner" based on everything else it does right

I've used 2 boards with channels 1&2 and both have worked fine.

Edit: my memory rated at 2.5-3-3-7 is running at 2-3-2-10 at 215 FSB and did 245 at 2.5-3-3-10
