A64 Nforce3 150: Syn vs Asyn Memory

[sexsymbol]

Actually I´m setting up my rig, doing stability test, etc. I was wondering if it was worthy to run a high HTT with asyn memory. So I´ve done a series of benchmarks to know which option gave better preformance. This are the results:
Rig1:
- Mobo: Shuttle AN50r fully modded
- CPU: A64 3200+
-Memory: 2x256 BH5 Kingstone
- VGA: 9800XT

htt: 240
memoria 1:1: 240
micro 10x: 2400
ldt 2.5x: 600

sandra: 3727
3dmark03: 5464
3dmark01: 16733
Super_PI 1MB: 36sec

Rig2:
- Mobo: Shuttle AN50r fully modded
- CPU: A64 3200+
-Memory: 2x256 BH5 Kingstone
- VGA: 9800XT

htt: 300
memoria 5:6: 240
micro 8x: 2400
ldt 2x: 600

sandra: 3722
3dmark03: 5454
3dmark01: 16685
Super_PI: 36sec

wtf? 16685 points seems extremly low to me... you are doing something wrong...

I´ve been using this windows installation for several days, lots of resets, locks, etc. No nforce drivers installed and the driver I´m using for the ATI is pretty old. No windows update, no tweaking at all. I wasn´t looking for a high 3dmark, only looking if it was worthy to run a high HTT.

[EmineM]

well you wont be able to find out if you dont even have the mobo drivers installed.

[sexsymbol]

I forgot to include the settings XD.

[sexsymbol]

The setting are exactly the same, except for the HTT. The conditions are the same for both. My intention was te see if it was faster and indeed it is the same or a bit slower. I know it is a crappy windows installation, but it is crappy for both.

Leave the LDT at 2.5x for the 5/4 memory rig. No one would lower it to 2x at 300HTT...and that's why they'd see a performance increase over 1:1 at 240. ;)

[sexsymbol]

I was looking for the most equal situation. But anyway my mobo won´t handle 2.5x300. It locks up at 290.

with a very similar rig I was getting 23,500...

that IS low...

[lalPOOO]

no chipset drivers (plus other things he said)... please read :p:

sexsymbol, its not kingstone, its kingston.

I know my 3dmark result is not a world record (The thread title doesn´t mention about 3dmark), I was only looking for the benefits of a high HTT and if asyn memory gave better results than in nforce2 mobos. Asyn memory works exactly the same as syn memory, but there is no benefit of using a high HTT.
Thanks for the spelling correction lalPOOO XD.

Whats the maximun stable LDTxHTT combination you can get?? I barely reach 700.

I'm liking your tests... not for the high HT but for the mem doing ok at 6:5... good for those that want to use there BH5 in case they get big cpu clocks. Being able to do what intel people have done for awhile now is nice.

Regardless of not going for records, lets get the drivers on there though so its more real world.

I think the results are no surprise.... Most ppl still have the stigma that running with memory dividers are BAD because of the P4, but this is no longer true with the A64 since the memory controller is IN THE CPU, so it's TOTALLY separate from the FSB. The performance of the memory should be identical as long as its run @ the same clock and timings.

Are you saying its normal to run 2.5x LTD @ 300HTT???

AFAIK 265-270 is max HTT with 2.5x .. i have never seen a nf150 do over 280HTT with 2.5x LTD. 3dstable that is.

My AN50R could do 270 with 2.5x LTD.. untill i tried 2x .. after that 264 HTT is max running 2.5x .. Im starting to dislike it :mad:

[HKPolice]

I can do 2.5x285HTT prime stable, but haven't tested 3D. I think if it doesn't crash after you change the clock, it will be stable as long as your CPU and Ram can hold up.

The secret? COOL YOUR NORTHBRIDGE. The stock heatsink is stuck on with cheezy DOUBLE SIDED TAPE, only making contact with the corners of the chip. I bet the chip would overclock better without the stock heatsink....
