I suppose people wouldn't generally be looking in here if they weren't having trouble, but it seems from reading this thread that there are tons of people having trouble with this combination.

Athlon 64 3500+ (Newcastle or Winchester)
SLI Deluxe motherboard
6600/6800 GT

I've built a bunch of systems before, but it sounds like this one is going to be tough. Is it worth trying this setup or is it just too prone to have problems?

Steve,

The system can run stable, are you up for the challenge? At least you know where to go for answers to FAQ's now

Good point, Mike.

I guess while I'm here, I might as well ask another question. My intent for building this system was to buy one video card now, leaving myself a fairly inexpensive upgrade (second video card-SLI) a year or two from now. Is it going to be an issue where I can just flash the BIOS to the current version on the old video card so that it's the same as the new one and it'll be a go?

Just an FYI,
I have made great gains this weekend by swapping ram (Corsair PC4000 Pro to Corsair PC3200XL Pro) and updating to Bios 1004. The system is running much better, however.....still not Prime95 stable, even non overclocked. I was able to reach 300FSB with a 3:2 divider and was prime stable for 1 hour 9 minutes. Seems things are getting better, there is still work to be done though.
My current setup:
Winchester 3500+
A8N SLI "Satan Lives Inside" Mobo (whoops did I say that?)
Corsair PC3200XL Pro
2X XFX 6800GTs
Enermax 535W SLI power supply
2 80 GB Sata drives not in Raid array

Mike:
Thanks for the help, i put DVD RW to MODE 4 in BIOS, in windows , it showed me "Multi-word DMA 2", but then i changed it in windows to Ultra DMA 66, it looks abit better, 1 G for about 1 min.
i ran Prime 95, and gave me same erroe everytime, the system is not OCed, is this realated to IRQ problem? also, the vide card driver seems to uninstall itself sometimes when i reboot. dont really get it.
again, thanks for all the help!
Lu

1 Gig for 1 Min is a big jump from 2.5 Gigs in 6 Min


******UPDATE******
DVD will be 22.1 MB/s transfer rate
CD will be 7.1 MB/s transfer rate

The numbers you are showing here are for CD rates.
22.1 MB/s X 60 = 1,326 MB/s
1,326 / 1000 = 1.33 Gigs per minute

7.1 MB/s X 360 Seconds = 25,560 MB/s
25,560 / 1000 = 2.5 Gigs for 6 minutes

I think during testing you are changing from DVD to CD. lol

.

I guess this method works.

What are your mem timings at?

What version of Video drivers are you using? 6x.xx or 7x.xx

Mike :)

Mike Thellend

I have some qestions.
I am oc my system and it is going well, but I am wondering about what temperatures
would be to high? What temperatures would you recommend?

My system

AMD 3500 winchester @ 2704.
HTT 284,6.
HTT Multipler 4x
Multpler 9.5
Corsair Twinx 1024-PC4400 c2.5.@ 2.5-4-4-8
2# Gainward GeForce 6600 Gt GLH. @ 560 - 1.2
2 Hitachi 250K Stripe0.
Thermaltake Tower 112 with 2 fans.
PS bZerk 500W.
4 cabinet fans.

System is stable. cpu idle 35c. cpu load 44c. Motherboard idle/load 34c.

Something is odd with the temperatures. The temperatures listed abov is from Asusprob.
When i stresstest with Sandra, the temperatures shown here is the opposite.

When it comes to memorysettings I can set them more agressivly, but it changes very little.
My 3D Mark 2005 score is not to good, 5699. Is this not a little low?
I have followed your exelent guide on page 16. Thanks!

Steve,

I would purchase the most current card. PVT45FUD.

Bios in not an issue, and flashing is quite easy. I really can't tell you if the PVT45FUD will be available in one or two years from now, but I'm sure you'll be able to get a used one on EBAY.

Mike :)

Sander, (or anyone else for that matter.lol) I posted a screeny of my CPU-z memory tabs a few pages back and was wondering if you have had time to try and figure out why my OCZ RAM won't work in dual channel mode. I am also curious if the RAM could be the cause of my ongoing stability issues i.e. random freeze ups. One of my friend asked me " Why do you care you still have a mb of ram." That's not the point. Dual channel DDR is not bleeding edge technology and by gosh it should work on a bleeding edge board!! Thanks again for your help. Kevin :)

>> Re: Asus A8N-SLI FAQ
I have an idea!

Why don't you and Sander trade? I'm sure Sander has a few hundred sticks of RAM laying around, If Sanders RAM is working and you put it in your board and it doesn't, then you'll know it's your Mobo or controller. Who's to say you won't get another bad batch of OCZ. This would be a sure way to find out as his ram works in dual mode.

Vice versa, if Sander gets your RAM and it doesn't work, then he can Analyse it. If he is unsuccessful in getting the RAM fired-up, then you'll know it's a second bad stick of RAM from OCZ, then send Sander his RAM back.

Kevin I know your stuck on the idea to get that OCZ working. lol

I do believe you both have the same RAM? 2 x 512mb OCZ EL Patinum Rev. 2 DDR400 PC3200 RAM



Place your bets ladies and gentlemen;
RAM
Controller
Mobo
$20 bucks on Mobo. lol


PS: This forum is so popular now, they probably know already! hehe

Drum roll please!
Will Sander do it or not, the million dollar question pending on Hardware Analysis.
Sander, your fans are waiting for you.

Great idea Mike!! Let's see if Sander is game for a swap. Heck I'll even pay his shipping! I'm still trying to find some ram to try but I believe I'm going to have to buy some inexpensive ram to see if it works. Think they'll get wise at Best Buy if I return 20 minutes later wanting a refund! :)

P.S. I've RMA'd the mobo and the ram over this issue so my money is leaning toward the controller.

Remi, There is definately something wrong. I have a similar system (with the exception of the GFX card manufacturer and I get 8224 in 3dmark05 with no oc'ing and 8550 oc'd as per Mike's post on page 16. After the Ntuning sessions my gpu #'s are 380 , 1.02 . My CPU is at 2.4ghz+/-. Temps are 31C CPU, 40C mobo??, and 46 and 50 on the GPU's. #1 gpu always runs a little hotter (3-4 C) than # 2. I suppose it's because of their positioning. I also have a 120mm fan in my Aspire X-navigator case blowing right onto the GFX cards. Good luck.

Mike, how much notable difference does Dual channel ram provide over single channel? Just curious.

A very big difference, it doubles your bandwidth.

As for the RAM itself, "dual channel" RAM is exactly the same as "single channel" RAM. There is no physical difference in the memory itself - the only difference is that the dual channel kits include two sticks of RAM (hence the dual). It basically doubles memory bandwidth on a system that supports it, so provided you have two sticks of RAM and a system that supports it, it's basically free performance. Companies selling RAM as "dual channel" are just cashing in on the name because there really is no difference. You can take any two single sticks of RAM and provided they're the same specs, they'll work fine in dual channel mode.

Mike :)

With the PCZ rev 2 RAM I dont believe that the SPD will ID the RAM correctly as the times are tigher than any other RAM on that speed,

HTT @ 4X is fine, especialy if your clocking, 1146 is the abosolute top, you WILL start cooking at any higher, Check with CPU-z that you have the REV3 chip, NOT the REV - the rev3 is solid black and the 2 has a metal ring. this is essential as the REV3 is the ultra NB chip.

alot of the MOBO readers give the reverce temp readings, this is not un common as there not fully geared up for NF board and the mofets that are on them.

you best bet would be to goto this site http://mbm.livewiredev.com/download.html and get a copy of MBM5 its accurate and in some cases will require manual settings.. FUN there is a list on the website of all supported boards.

PCI and USB device errors, there is three reasons PCI express bleed, To higher speed on the NB (over heat) wrong not updated drivers. note that the ASUS NF4 drivers are enhanced!!

they to keep the HTT equal to or less than 1000.

N tune causes a performance DROP, using the Nvidia tools, will rest the clocks on your system, even if you only open the display properties.


____ Crucial ballistix 500 works fine at stock and upto 259Mhz. (yes I know that only 10Mhz) I have not been able to test higher..--

20 pin and 24 pin ATX PSU on Asus sli ? If your running ONE card (GPU) 20 pin is required, with a 24Amp 12 RAIL.

20 - 24 pin convertion?
NO there is a difference between the two and single rails, The noase level is lower on the 24 pin native and give a cleaner power supply even though on a lower ampage ( to rail add to more that 30 amps in most cases.

FORTON ESP 12V - works there is also a 520 watt one, which should also be fine, I have not reshaed this as of yet fully. But with what I have seen there fine ( i was going to get one for mine) these are used on servers, so you can max you drives out if you want.

Here is mine http://www.gloucestertraining.no-ip.com/temp/pc3.jpg

As you can see its just sat about waiting now..:(

ofr the mo its just this one :) still a 3200 at fx51 speeds, and performs like a 6800 ** just better

I have a question about choosing the right strip block size for my RAID0 SATA disks setup. ASUS's recommendation is 128KB for performance disk usage. But in the NVIDIA's nforce manual, it seems to suggest 64KB is the best. My guess is if my machine is purely for gaming, choosing 128kb is probably the optimal solution. But as an avid digital photogapher, I have tons and tons of digitial photos with sizes from somewhere between 500kb to 3mb each. For both performance and storage reason, do you think the 64kb strip block will be better?

Another concern I have is I saw some postings about NCQ actually slightly degrades the performances of the disk throughput, is it true? I bought couple Seagate 250gb NCQ HDD, hoping to get better performance than a non-NCQ SATA disks. Do you think that was a waste of money? Also are there any benchmark testing I can do to prove this NCQ capabilities?

I appreciate any feedback you might have and thank you for this wonderful forum!
