Combination is questionable for me at best with requiring 2.9V to the memory to come even close to rated speed of the module in "Synch" mode. CPU seems to have some headroom due to only using 1.65V right now. Using XP 2600+ 166FSB version with 12.5X stock multiplier. Will try different modules soon. 250FSB and 11X would be nice. :D
Lookin good, Gooch :)
2.9v & only 200MHz sounds low.....messed w/ the timings at all?
Something don't smell right there :p
I'm running two sticks of Corsair 3500 at 211 with 2.77v and it seems stable. The only time it does not seem stable is when the room temp is warm and so I think that is more likely a northbridge issue than the memory.
Have you tried individiual sticks to see if one is slightly below par ?

Single 512MB 3500C2 for now. Was thinking of getting another module for dual channel action but I am seeing other people having problems with the Corsair modules on this board. Might be the first RMA request with Corsair of not doing 217MHz at default voltage at 7-3-3-2 timings. I can barely hit 200MHz in synch at 2.9V with the rated timings from Corsair. Maybe some Mushkin, Kingston Hyper-X, OCZ or Geil in the next several days. :)

What type pf cooling do you have? im gonna get corsair 3500 and a 2400+ and im curious to see what people get on air..
The 8RDA+ is on KryoTech SuperG2 due to my KD7-R is in Prometeia right now.
not fam. with those, but take its liek a prommy/vapo. good stuff.
Found out my memory is seriously holding me back. Turned down multiplier to 11X with 1.9V to XP 2600+ and memory to 50% of FSB:
What's the Sandra memory score when running at 50% ?
1.9v and 2.7ghz!!! Woah, how far can you take it with more Vcore? And any benches at DDR500?Quote:

It sucks. Running anything in a async function unfortunately ruins the performance. Massive bottlenecks are created and so on.
Bandwidth basically is lousy at 125MHz even at 4-2-2-2 timing:
The board/CPU are totally stable @ 250MHz FSB? Seems as tho good memory is the only thing keeping us from running our AMD setups @ 250FSB then...... :)
Seems to be stable but of course I need to run prime 95 for at least 48 hours straight. Just made a 3DMark run and saved the 3dp file due to MadOnion seems to be down for me right now.
CPU Arithmetic:
CPU Multi Media:
Very nice...I'd LOVE to see a compare URL @ 250MHz FSB :D
BTW, don't you have any other memory ratio's to choose higher than 50%? Say perhaps 70% or higher? And if so, do they work? :)
Yeah, doesn't 80% work? With a FSB of 250Mhz and mem running at 2*200Mhz, you should have some nice benchies. :)
I don't know why they can't get better scores out of those nforce 2 boards if the fsb is at 250 and the ram runs at 200fsb dual channel. There should be plenty of bandwidth available and the cpu can actually use it at 250fsb. Maybe a later bios will let you run asynchronous like that without so bad of a performance hit. I was hoping it would run fine from the start that way I could run my processor fsb way up and still use my samsung chips on the board at 200fsb. Dreaming of 400fsb and dual channel ddr running at 200fsb.
i too have a stick of that corsair 3500 c2. and it too needs like 3.15v to run stable at 195 aggressive on my AT7 Max2.:mad:
Well if you're talking about sandra scores, then SiSoft said their program doesn't read Nforce 2 properly...on my 8RDA+ it says unknown motherboard.= with the 2003 version.Quote:

when running asynch latency makes your performance worse (a lot), so the only solution is running synch (I know, it's hard...)Quote:

Yes, I wish I could run 250:250 synch. :D Well, the options for memory to fsb ratios are 50%, 60% 66% 75% 80%, 83%, 100%, 120%, 125%, 133%, 150%, 166% and 200%. Here is Sandra memory at 250MHz FSB with memory at 75% or 187MHz at 6-2-2-2. I can not get the memory to run at 200MHz reliably at synch or asynch using a single stick of this Corsair. Here is Sandra at 187MHz:

I'm having a few problems with my twin sticks of similar memory at present.
I put the new BIOS in and at relaxed 2-7-3-3 settings it went up to 225 fairly easily. I tried it at CAS 3 to see what the performance hit was and then it wouldn't boot up. I believe Asus nforce2 boards have this problem as well. So I took the memory out, put in some Crucial, cleared the CMOs and booted up again with the dual Corsair.
It was running pifast at 217 but over the course of the evening it went down hill and now it will not run at 211 ! I had this the other day as well, it seems to have good and bad days. Temps during the evening went down and voltages went up, but no joy.
3dmark couldn't get past the car chase as well. It sems to be when I have the cpu above 2100 and the memory above 200 ( though the processor runs at 2300 with 2.1v.)
I'll have to reseat everything again and put the multiplier down to 8x and work my way up again.
Does anyone elses day to day runs fluctuate so much ?

Andy
Gooch,
Thanks for that...looking at it...I'm really not impressed w/ NF2's 3DMark scores yet(even taking into account the 50% mem)...I still might get one someday to play w/ ;)
Fun to play with until they get the bios working correctly for some synch action. There seems to be some bandwidth even for 64bit single channel action at 233MHz synch. Absolutely no 3D though! :p
Got 3D to go at 225MHz 4-2-2-2 synch. :D

Very nice:)
Any v-mod for the Epox yet?? mem and cpu
OPP
Nothing yet. Bone stock. :p
DaGooch: is that 211Mhz dcddr or not?
The highest DCDDR sync 3D mark stable I can get is 200Mhz. This is with 2*256mb corsair xms 3200 @ 7-2-2 CL2:
14886 with a ti4200 at 330/590
That's a huge leap from were I left with my 2.4B @ 3150Mhz, almost 1000 points more! :D
Not bad man . Here's my year old 8k3a+ board with §§§§ty ram timings 2623 2t at 297/600. No tweaks just slider set at best performance. I just don't see the NF2 as a good upgrade for me at this point. If I could get my core any higher, we would have pretty much the same numbers.
http://service.futuremark.com/compare?2k1=5325950
Believe me, 30mhz in core doesn't make a 1700 points difference, more like 300~400 points.
Single channel with 4-2-2-2 timing. I finally got the board to work in synch above 200MHz by taking off the 133/166 jumper on the board. Strange but true. :DQuote:

You took the jumper right off the board? What difference did it make for ya?Quote:

Thx.
Oh I believe you but my ram timings are much slower than yours also because of this $60 ram I have which also makes a difference. There is a speed increase of 500 3dmarks. Many people will like that an buy the board but I'm just holding out for more performance. It's a good comparison anyway of what speed benefits you will get from nforce 2 as far as games go. There is a slight difference but nothing to get excited about.Quote:

does all the onboard stuff like sound and raid work
@ 250 fsb?
btw, nice work :D :toast:
Well obviously it let him run sync over 200mhz ;) :pQuote:

Before I was able to only do 190MHz FSB in synch mode. Now doing up to ~ 217MHz.Quote:

Yes, but memory was at 50%.Quote:

Awesome, I'm gonna have to try that 1!!
Thx Gooch.:toast:
did you toy with any other ratio's than 50% @ 250 ?
I guess the PCI lock really does work....
looks like I'm going to have to dive in:banana: :banana: :banana:
I can't get dual ch ddr to finish 3dmark no matter what timings in the 180-200 range. In single it runs fine. this is with twinmos 3200 512x2. I wonder if any mem out there can get over 200 in dual on this board?
do you have your cpu setting to agressive or optimum to get this?Quote:

Optimal for now. Will try aggressive to see if it makes a difference.Quote:

Got some Kingston Hyper-X for single channel DDR action and system is stable with CPU setting set to agressive:

http://service.futuremark.com/compare?pcm=929342
Just need 25MHz more on the memory! :D
Edit: Made it to page 3! Surrounded by P4 systems. :p

Very nice, Gooch! Go go go :)
i have 2x256mb twinmos pc3200 with twinmos chips and can run dual channel mode up to 213 mhz sync with 2422 timings.
so no fsb or dual channel problem for me here!!!
hmm getting my corsair 3500 cl2 and the 8rda soon - will post my results then :)
cya
what kind of cooling are u using on ur cpu dude?:confused:Quote:

He answered this earlier in the thread... Kryotech.
I want to know if he's doing anything special for NB cooling though.... GoochMeister?
sounds good. Are you running in sync? I just got 2 sticks of the hyperx today and want to try dual, but your single seems plenty good. what voltage are you using for the hyperx at 225? Any other suggestions for how to get that stable? You still using c10 bios or the new c16?Quote:

Also, can you now complete 3dmark at 200-2xx?
