A7N8X Deluxe rev2 and Corsair XMS TWINX4000PT

Recommended Posts

1st post...

 

ok, here's what I'm running:

 

ASUS A7N8X Deluxe rev. 2

AMD Athlon XP 2800+ Barton Core .13um

2x256mb Corsair CMX256A-3200C2

BFG Nvidia GeForce 6800GT 256MB(factory OC'd)

WD 36GB 10,000rpm Raptor SATA

Seagate 80GB 7200rpm SATA

Lite-On LTR-52246S CD/RW

Generic 550W ATX 2.0 PSU

ViewSonic G90FB Black 19" CRT Monitor

ASUS A7N8X2.0 Deluxe ACPI BIOS rev 1005 (Phoenix)

 

As u can see i need better everything...but...

 

I can afford at this time only more RAM, which i will also beusing in the A8N32-SLI Deluxe Mobo I intend to buy in '07, so........

I bought Corsair XMS TWINX4000PT 500mhz...now for the question:

 

I know it's compatible with my current Mobo as per Corsair & ASUS sites, and I wanna use this RAM.....NOW and I'm concerned with achieving synchronos clocks.

 

Ive read the excellent post (even have copy of it) concerning the 2800 and RAM sync issues and resolutions....but I need simple step by step how to without all the whys etc. My main use for this comp is online and single player RPGS.

 

So, Ramguy...I want to get the 2GB capacity from the new RAM (until I can get Nforce4 board) and at the same time I'd like to "sync" the clock speeds on the Nforce2 board....all w/o losing my mind :biggrin:

 

Programs I have:

Memtest86

CPU-Z

3dMark 05

AquaMark3

 

On current setup with stock clocks i get 5200 in 3DMark 05

 

ANY assistance and/or recommendations would be appreciated....ty

CAS Latency (tCL): 2.5

RAS to CAS Delay (tRCD): 4

Row Precharge (tRP): 4

Active to Precharge Delay (tRAS): 8

Memory speed: 166 Mhz / DDR333

 

Memory Voltage: 2.7-2.8 Volts (Warrantied up to, but not over, 2.90 volts)

All other settings to defaults.

Make sure you remove the old memory, and next time please post in the CORSAIR area of the forum.

I aprreciate the fast response, and have already the Corsiar testing articles, however this does not answer my question concerning running sychronous clocks or at least getting up to the 400mhz the nf2 board supports or wether I should even TRY....I know HOW to do it I am just not sure if its worth the effort

 

Is ur response saying NOT to try raising the FSB etc becuase the gains arent worth it?

I guess i am.....I want to get the most performance out of my system with the

Twinx2048 4000PT with the NF2 board until I can get the NF4 board.

 

these are my BIOS settings, now with the 2x256mb Corsair CMX256A-3200C2

memory...(in 2-3 days I'll have the Corsair XMS TWINX4000PT 500mhz mem)

 

BIOS settings currently:

 

CPU Ext Freq.............................166mhz

CPU Freq. Multiplier setting.............Auto

CPU Freq Multiple........................12.5

Sytem Performance........................User Defined

CPU Interface............................Optimal

Memory Freq..............................By SPD

Resulting Freq...........................200mhz

Memory Timings...........................Optimal

SDRAM Active Precharge delay.............8

SDRAM RAS to CAS delay...................3

SDRAM RAS Precharge delay................3

SDRAM CAS Latency........................2.5T

FSB Spread Spectrum......................Disabled

AGP Spread Spectrum......................Disabled

CPU Vcore setting........................Auto

CPU Vcore................................1.65v

Graphics Aperture size...................256mb

AGP Freq.................................Auto

Sys BIOS cacheable.......................Disabled

Vid RAM Cacheable........................Disabled

DDR Reference Voltage....................2.6v

AGP VDDQ Voltage.........................1.5v

AGP 8x Support...........................Enabled

AGP Fast Write...........................Enabled

 

I realize I can NOT overclock and thereby effectively 'underclock' the NEW

memory and achieve sync....BUT.......I'd like to get the most performance outta my current setup when i install the new memory, AND I'd like to stick with the stock heatsinks and fans, for the simple reason that I'll be getting a new NF4 mobo in the future and at that time will put the 2x256mb Corsair CMX256A-3200C2 back onto this board and use the Corsair XMS TWINX4000PT 500mhz on the new NF4 mobo when i get it.

 

Summary: So what i NEED to know is:

 

When i put the new RAM in the NF2 board...what are the best settings I can use to achieve MAX gaming perfomance. Since I doubt that i can get a FSB of 500mhz to sync with the RAM freq.....I need info on the "in between choices" as I'd rather not spend anymore money on this old board (ie Zalmans, water, or any other excess cooling) (my comp sits right in front of Air conditioner now.....and i have a rear 80mm fan blowing ....IN....to bring the chilly AC to my case :) )

 

So im looking for the best middle ground i guess. Sorry to make this difficult but budget contraints force me to upgrade in baby steps.

Yea i guess...i know i cant run the RAM at 500mhz at 1:1 with the FSB

But i hate the thot of running 500mhz RAM at 333mhz

 

I guess i need to know if getting the fsb to 400 with AMD stock heatsink and fan is possible....I mean if i absolutely HAVE to...i cud pick up a zalman.

 

So Im wondering if i can get 400 snd what the timings and (if needed) voltage settings etc aiming for 400mhz FSB would be?

 

Also wud running 400mhzFSB 1:1 w 500 mhz ram be faster that running async at 333 or 400 FSB?

Ok heres what i curently use and my current settings:

NOW..........I am upgrading in baby steps (budget) and I plan to Upgrade my current Mobo , CPU, PSU and Vid Card in 2007.......for now Ive have just purchased.......................... Corsair XMS TWINX4000PT 500mhz...........

 

 

This memory is compatiable with my current NF2 mobo....what I plan to do is use the Corsair XMS TWINX4000PT 500mhz memory on the NF2 board till i can afford the ASUS A8N32-SLI Nf4 board and I'd like to get the best possible performance (gaming) out of my current setup with the new RAM and with the stock heatsinks and fans i have now.........(my comp sits right in front of air conditoner btw and i have an 80mm rear fan blowing INto the case and another 80mm exhaust fan on left side of case. Also using the stock heatsink/fan setups that came with the CPU and Vid Card.

 

 

So....i guees I'll need to OC my FSB and delve even further in to the 'dark art of OCing' with this new RAM. I realize there is NO way i can achieve FSB and RAM freq....sync......at 500mhz with this setup....but Id still like to get the best performance I can in the mean time. I mean would it be better to OC the FSB and run synced at 400mhz, or leave as is and run synced at 333mhz?

Or, do i even have to worry about sync? Out of these 3 options, which would be my best gaming performance choice and then what BIOS settings would i use to achieve this.

 

 

Programs I have:

Memtest86

CPU-Z

3dMark 05

AquaMark3

 

On current setup with stock clocks i get 5200 in 3DMark 05

 

ANY assistance and/or recommendations would be appreciated....ty

You have to run the memory in sync with the CPU with this MB or it will not be stable. This is a limitation of the memory controller Like Specmike has suggested in a previous thread!
