cool matt, looks good. Have you run any mem bandwith test is sisoft ? currious how they look.

Hello Major Slaughter
I will post some in a bit, its seti benchmarking atm :)
do you want to see the max I can get or the max at a fully stable speed?
both would be nice :D
have you tried it in single channel and dc ? I had my NF7-S stable dc sync at 220, but to my surprise I could get 230 single channel to pass 3dmark and had better bandwith, Opp has his running 237 single channel and got 3600+ mb/s
Where can I get one in the US:)
here's the 230mhz single channel
I will have a go, I am trying to get a Sub 2hrs Seti benchmark, the best so far is 2.01, so that may help me :DQuote:

Hey matt, I ment to ask too about the bios for the 8RGA+ does the fsb go up in 1mhz increments ? and where does it top out at in the menu selection?
My complaint on Abit is once you get over 200, the increments start taking some leaps 200,...210,215,220,230 etc... and only tops out at 237 which isnt hight enough at least not for Opp ! hehe
It goes in one's upto 250, not that I can get there yet :D
thats good, keep trying you might wish it went on up some more.
8RDA+ Single Channel

Nice spaceboy.
PUSH that sucker M@tt. :D 2.01 is great for an XP1700!!! :slobber: (even with a Prometeia...)Quote:

Nice results Mike - am surprised that Epox is releasing pre 1.0 rev boards to the public (at least to direct retailers, not just reviewers).
Do you have to set the VDD up to 2v to be 3D stable @ 219fsb or can you run with lower values?
If the bios is _similar_ to the 8rDa+, then you might want to try the known tricks to reach higher FSBs...
- For Dual Channel, use slot #1 and #2 (closest to CPU) and try to use slot #2 with 1 stick only
- If you have a JCLK jumper (11/133/166fsb) on the board, then remove it
This thread submitted by Muzz has been helpful to quite a few folks (believe it or not, this JCLK jumper trick helps and I can't understand why... :) )
Good luck and thanks for keeping us informed.
Cheers!

I just need that lovely XP2100 you have or one the same :DQuote:

Yes the VDD does need to be at 2v, I raised the fsb slowly and needed the VDD for sure.Quote:

Thanks for the tips I will have a go tomorrow, I have had enough of the PC today now ;)
I thought I better post a follow up, after 6 weeks or so of running 2.0Vdd on load running Seti 24/7 the board died, it maybe just a One off, but I thought I would let you guys know.

It looks like a component failed and fried
On the plus side the board was replaced cost free.
Wow!....I've heard of that particular chip failing with the kind of results you've graphically shown. That chip runs hot even when vdd is at the standard 1.55v. I wonder if putting a HS on it or blowing some air across it would prevent that kind of result.
i hope it can be cooled by HS since i have the same board running a vdd 2.0 with no current heatsink on that particular chip.Quote:

Hey M@tt how have you been ?
This has got me thinking about putting tiny little hs on every chip that gets warm to the touch on my mb's.
Is that the vdd regulator on the 8rga+ ?
Hey M@tt, I have an 8RGA here.
They are very inaccurate. I have Prometia cooling too.Quote:

My 8RGA and 2500+ Barton AQUCB reads 20C at 1.85 volts! The prommy evap temp is still -34C. I was worried initially but after mounting it three times with all the washers I decided it was a sensor inaccuracy. Now I just ignore it, heh.
As for overclocking, I have been unable to run my RAM above 205MHz. If I set the DRAM to 50% of the FSB rate I can get my FSB to 220mhz at 1.8Vdd no problem. I have been wondering how to resolve this and thought that it might be because I have been using the onboard graphics so far. This is with the DRAM at 2.9v.
I just tried adding a small AGP video card to disable the NF2 onboard video, to see if that was keeping me from getting better RAM speed. The RAM still won't go above 205MHz. I have two 512mb sticks of rev. 1.1 XMS3500 Corsair (same as you) and I have tried each one, one at a time, in slot 1 just to make sure one of them isn't bad. So either both of them are bad, or the problem lies elsewhere. This is a really kickass board and I don't want to put my 8RDA+ back in since mounting the Prommie head is a six headed §§§§§.
What do you think? Is it the RAM?
Hello Major Slaughter bar the dead M/B everything is rosy :DQuote:

I do believe that chip and maybe the one next to it are to do with VDD, I now run 24/7 at 1.8 just incase ;) I am not sure what the shop would say if I killed another board, although as the settings are in bios, I don't really hold myself to blame. I am sure it would be a good idea to cool that area of the board.

Try these bios settings if you want
In advance chipset
System performance = Expert
CPU interface = Aggressive
Memory freq = 100%
Memory timings = Expert
try 5-2-2-2 I found the default settings that lower with high fsb's were not stable.
AGP Clock freq = 66 Mhz
Integrated peripherals = disable what you don't need.
The above is fine using an external GFX.
I found I got mine to run @ "only" 203 fsb 3-2-2-2 with the on-board GFX @ 130Mhz it produced a 5392 3DMark 2001.
The key to stability at high FSB using the on-board GFX is changing CPU interface = optimal, at aggressive I was having trouble even running at 166fsb.
With a GF2 Ultra it ran without any problems @ 215+ fsb with CPU interface = aggressive. 3-2-2-2
So it looks like the onboard GFX does hold you back, but not by much in the greater scope of things.
All the above was in Dual mode BTW
I hope that helps a bit :)
Bingo! Thanks a lot bro, I didn't think RAM timings could be holding me back so much, especially with the XMS3500, since it's such good RAM.Quote:

newegg has them in stock:

Not the regulator itself, that's the IC next to it, it's a MOSFET. :) You've got me worried now too, mine's been doing 2.0 Vdd rock solid for the last few weeks...:slapass:Quote:

That's the exact same mosfet i fried on my 8rda+ at 2.0v. Maybe we should slap a small heatsink on it?
