A64 3000+ overclocking results

Specs are in sig.

2025 ghz (9x225 HTT 5x)
2GB Kingston Value Ram 3200 (225 mhz) (2.5-8-3-3)
6800 Ultra (431mhz/1.13mhz)

Sisoft Results (CPU 9128 Mem 5200)
CS: Souce (114 fps average) via stress test

I can run the processor alot higher, but at that point the 2gb ram defaults to 166 and won't boot, so I would have to use 133 and the drop in memory performance is not good at all. At the above settings I see a nice increase in cpu and memory peformance.

Temps 35 idle/45 load

Prime95 stable for 14 hrs
 
Its possible, but I think I have reached the highest 1:1 on my ram....so need to research at what next fsb the ram would run at 225.

Looks like the next FSB would be 275x9 with a divider of 166mhz for a clock speed of 2475. But the divider seems to not work for some reason, the system just wont boot even with the voltage raised, the ram refuses.
 
Your 2Gb, is it one stick, two 1GB sticks or four 512MB sticks? If it's the last one, you'll probably have to reduce your mem command rate to 2T in bios. If it's not, you might want to try it anyway. Plus, is your dimm(s) double-sided? Some mobos default to DDR333 speed if you use double-sided dimms.
 
225 on value ram is awesome...you could OC the crap out of that puppy if you wanted to and not have to run that much lower dividers....
 
2 x 1gb, but usually more expensive. Most 1gb modules have really loose timings like 3-4-4-8 but the ability to use 1T command rate more than offsets the loose timings. Kingston makes some 2x1gb HyperX kits that have 2.5-3-3 timings but they are $700

For performance and overclocking 1gb is better than 2gb.
I would only recommend 2gb to those who use their machines primarily for video editing and encoding, CAD, Software development,etc....

If gaming and or general desktop apps are the primary usage stick with 1gb
 
I couldnt do anything with my board until I took the HT down to 4x, running stock HSF @ 11x 225. Do you think I'll get much more out of the chip if I drop the RAM down to 166. I have the K8NS ultra too, but I dont see RAM timing ratios, only speed. I bit new to this. I dont want to go out and get more noisey fans, just want to see what I can get out of the chip, its a 130 newcastle core
 
Start your own thread and list all your settings, I'm sure we can help 🙂

Neurorelay, 2T might help, but it really kills A64 performance. Run your RAM at lower timings and give it at least 2.7v. Try 270x9 and see how stable it is. You have ot try all different settings before you stop :thumbsup:

Everytime I try to boot at 1T (in bios the option is to disable 2T timings) the system locks up.

 
Okay...bumped the voltage on the ram by .1 to 2.7 and then adjusted the tRAS to 10 and BAM! I am running at 1T. Now, with 1 gb, there is more of a difference in 1T then with 2gb. At least I am getting around 5200 in Sandra.

On a side note....getting around 127 fps at 1280x1024 with high settings in CS: Source stress test.
 
114 to 127 is quite the boost, that's why I mentioned going to 1T 🙂. Now try knocking your LDT multi down to 3x and put your memory at 166, and see if your system will boot at 250x9 (make sure you're at 1.5vcore at least) and see if it will boot. Then keep raising the HTT and see how close you can get to 270x9 (stress testing the whole way). I think you'll be able to squeeze alot more performance out of your system :thumbsup:
 
After a little research on some UK sites...I found that an older bios version for my board would possibly give me a functional 166 divider. So I downloaded the F4 bios and voila, it worked.

I am now running at 9x245, with a 166 divider (memory is at 200mhz) and I couldn't be happier. LDT at 4 x HTT of 245 = 980 FSB.

CPU at 2205 mhz (3500+ basically)
2GB ram at 2.5-8-3-4 2T

Sisoft
CPU 10000 (competitive with a P4 3.6 ghz)
RAM 4600

CS:Source
FPS 125 fps

So 400 mhz overclock with no voltage increase. Idle at 38c with a load of 44c. Okay, time to enjoy the setup now, got what I wanted and performance wise I should be good for a year or so. 😛

What I noticed is setting 2t takes about 1000mb/s off of my sandra scores...what does that mean to the real world...very little in certain apps and a bit more in others.....Depends if apps are bandwidth sensitive or just more cpu dependent...One thing I would consider is using any divider that can allow you to run the tighest timings along with 1T...You will be surprised bandwidth doesn't necessarily mean as much with the A64 architecture versus say the P4...

My system running 133 divider and cas 2,2,2,6 is better then my system running 166 cas 3...166 cas 2.5,3,3,8 is the fastest (not by much in most apps I tested) yet if I threw 2t in there the cas 2,2,2,6 and lower ddr speed would likely be the best bet...
 
By the way you should soft mod that card to a quadro...makes a big difference in 3dsmax.....Run specviewperf 8.0 and then post your score and I will show you mine...They have a max test and a lightwave test in it....
 
hi guys, new to the forum and to over clocking. i been trying to play around and see how i can push the system, when it stoped at 2025mhz. i know what i have done is wrong some where, so any help is most welcome. please explain in some detail as i really have little understanding on the art. what do i need to do to reach the 2.4s or 2.6s i have been reading about. i downloaded cpu-z as tool to help me. these are my specs:

AMD Athlon 64 3000+ Winchester
Voltage 1.584v
Core Speed 2025.0MHz
Multiplier x 9.0
HTT 225.0 MHz

Memory Timings:
CAS# Latency 2.5clocks
RAS# to CAS# delay 4c
RAS# precharge 4clocks
Cycle Time (tras) 8c
Bank Cycle Time (TRC) 12 clocks
Dram IDle Timer 16c

Spd timings table(2x512 chips)
frequency 133mhz / 200mhz
cas# latency 2.0 / 2.5
ras# to cas# 3 / 4
ras# precharge 3 / 4
Tras# 6 / 8

I have the stock heat sink.

What is your HT multi set to?
