good luck on selling off the mobo, and good luck once your new DFI arives, although I doubt you'll need luck with the DFI let's just hope you didn't get a dud chip, even if it hits 2.4 if its a dud then we wouldn't know normal ones could hit somehting like 2.6 or 2.8, although 2.4 would definately be nice as thats what the 3100+ Semps are supposed to hit, but with 90nm and SOI It'd be great if we can get higher.

Well, the Epox board is still new-ish, and I'm sure many people would love to pick it up for a cheap price. I'll try to pawn it off for $65 shipped, $60 if I have to. Negates a restocking fee, anyway, if Newegg allowed returns for mobos, which they no longer do. I'm fairly confident this chip will see past 2.4, motherboard permitting. After all, at the point where I was getting hard locks due to the chipset, the chip was doing nearly 2.2 on stock voltage.

Anywho, I ran some HL2 benches at 10x7 to see how things were stacking up!
3-5fps gain on a 200mhz slower chip. Not bad. Maybe 6-10fps at equal mhz?

Good to see some gain. Hopefully you see the 6-10 with equal mhz, and a good 14-20 at 2.6

Thanks for keeping me in the loop!

Bump in hopes of the DFI board coming in soon.

Fedex tracking says I'll get it Wednesday, but Fedex is always a day early on their fedex express saver. I just hate playing the waiting game. I'm also not looking forward to reinstalling another motherboard. My case has very little room to work with.

You don't happen to have benchmarks for an Athlon 64 2800 with the same setup? I'd be really intereted to hear about the performance differences between the socket 754 A64 and Sempron 2800s.

I do not, but there is an article on Anand that shows the difference between them. I think the difference was 1-5%. It's on there somewhere, check it out.

Cant wait to see ur results with new mobo

I want to get 90nm 3100+ and see if its better than .13

 

[Shimmishim]

the 3100+'s .13's don't o/c THAT well.

i hit about 2.5 on a prommy 1 unmodded with the dfi board.

the epox is a solid board but i hated how the vcore would change from boot to boot...

the only problems i've had with the dfi board is flashing the bios.

1 time i flashed a beta bios and killed that board (bad flash).

so i got a second board, placed the bad chip into the new board to hot flash the bad chip.

after the hot flash, put in the original bios chip back into the 2nd board and the 2nd board never booted again.

since then.... i refuse to get another dfi lanparty UT 250... then again I said i'd never get another DFI board but seems like these new DFI ultra nf4 boards are awesome.

dang it DFI... I HATE YOU...

 

[Avalon]

Can a wire trick be done to forcefully raise the multiplier on my chip?
Or a pin mod?

 

[Avalon]

I went into my BIOS after a reboot today, and set my HTT back to 270mhz and my command rate to 2T. Not only am I booting into windows now, but I'm priming stable. What does this mean? Is my memory controller on the sempron bad, or is it just that the Epox can't handle 1T at a high FSB(even though I'm using a divider) ?

What do you guys think?

*Edit*
2T performance at 2.28ghz is slower than that of 1T performance at 2.08ghz in HL2 on d2_prison_05 at 10x7 4x/8x by 79.9fps vs 85.3fps.

 

[blckgrffn]

good to know...

From what I'm hearing, not worth running RAM at 2T on A64 platforms.

I'm looking forward to playing around with my A64 2800+ "AX" and Epox 8KDA3I board. Received the stuff Friday, but am stuck 2 hours away because my car broke down (yeah yeah, I have a Ford). Hopefully I make it home tonight and some overclocking goodness should cancel out my depression over $600+ in car repairs.

I thought about getting the DFI board, but am willing to try the $40 cheaper Epox board first. If I end up not liking the Epox, will either sell it or put it in my fiancee's computer.

300HTT, 2.4ghz
Haven't had to touch my vcore, but the board's stock voltage IS higher than default voltage for a 90nm sempron. Currently, my board is sending 1.48v to my chip. So far that's been more than sufficient.

My idle temp says my CPU is idling at 35C now...that doesn't seem right to me. I notice that sometimes when I boot up, it says my CPU is at 40C, and other times in the 30s. I would venture to say that my temperature probe is significantly off, but when I prime, the temperature goes up accordingly. Actually, it could be because I have the porch door open, and nice cool air is coming into the house. My case's side panel is off. It was rather stuffy in here before, reaching around 80F ambient. It's about 72F ambient now. Anyway, prime is reporting a load temperature of 48C.

Agree with the 2T ram setting. It hurts your performance. I am only continuing with 2T in hopes that the limitation is in my motherboard and not my processor. I want to see the limits of my processor now, before the DFI arrives.

 

[MustangSVT]

90nm sempy 3100+ is more tempting now

 

[Avalon]

When I tried 305HTT, the system just kept rebooting before it even got to loading windows. I tried the usual round of fiddling with settings and increasing voltage, but no go. I am convinced that my limitations thus far are from this motherboard, and not my CPU. 265HTT at 1T and 300HTT at 2T are my max settings. Even running at 2.4ghz, this CPU has been priming stable. I will let prime go overnight and see how it goes, but it clearly looks like a chipset limitation to me. I never once had to raise my vcore to this CPU. It has more room in it yet :shocked:

The DFI arrives tomorrow. That is where it will really get interesting

*Edit*
Wth? I just booted into windows at 275HTT 1T command rate. It wasn't even letting me past 265 before?

Now running at 285HTT no issues at 1T.

Have you tried different ram, I know you used the mem divider and should take your ram out of the pic but I've seen posts with guys using perfectly good ram and a 100 or 133 divider and still having problems only to slap a cheap stick o ram in and problem solved. I can see that your ram worked fine in your old setup and is solid ram but maybe your new board just doesn't like it.

Wow, I just saw your edit after I posted glad to see you got it working at 1T
Good job,

I think it was something like that. I changed my TRAS from 10 to 8, and that seemed to be what gave me the stablity to go an extra 30mhz on the HTT. Now, most people I've heard of with this board were only getting 275-285, so I know now that I've merely reached the max this board can run. I am very happy. Although, the DFI will arrive tomorrow...so that will be additional fun

Time to throw a couple benchmarks in.

 

[Toro 45]

Keep us updated on the dfi and sempy, think it will get you over 300?

 

[DoC91383]

I may have to build a sempy system just to say i did if this goes well.

I am positive I will get farther. Most DFIs can do 325HTT stable, which would net me 2.6ghz for an overclock. That would be awesome.

I ran a quick bench on d2_prison_05 @ 10x7 4x/8x in HL2 running the CPU at 298HTT x 8 = 2.38ghz, and I got 90.5fps, which is pretty sweet. At 2.1ghz, I got 85.3, and my barton at 2.3 did 80.6fps

SuperPI your barton and ur sempron please =]

I'd like to see that too, I think he sold his barton but on a good day it should've hit 40sec 1M if he tested it at 2600mhz.

glad to hear that things are looking up!
