What kind of AMD64 3500+ (939 Pin) overclocking results should I expect? *update, my new system is up and running*

[demenion]

I am lucky enough to have in my posession a MSI K8N Neo2 Platinum mobo and AMD64 3500+ sitting in my room.

HOWEVER,

I can't use it yet because I'm stiill waiting for Newegg to ship my powersupply and zalman cnps7000a hsf. (i HOPE the zalman hsf fits )

Also, I bought some Hynix 2x512 PC4000 ram.

Since this setup seems quite rare i'm wondering what kind of results people have been getting with 3500+'s?

Thanks!

update:

well the zalman hsf and ram was shipped today...

anyways, I have no idea how to overclock this cpu to the max potential. i miss the old days when it was just fsb x multiplier

I'm just running it at default right now.... going to try overclocking after I get done installing updates and games.

update #2: scroll down for some benchmarks... 2.5 ghz is my limit.

 

[Dman877]

I'm gonna guess in the 2.4 to 2.5 ghz range on stock volts. They start at 2.2 right?

 

[iwantanewcomputer]

yeah 2.2. with that cooling 2.4-2.5 would be about right. some people have been getting near 2.6 with water

 

[demenion]

so default 3500s+ are 11x200? all of them are multiplier locked correct?

so I should expect to run at around a 218(436) FSB

 

[FullRoast]

demenion: Seems to me like you ought to be the one telling us what this combination can do.

 

[Concillian]

They are locked out of HIGHER multipliers, but not lower.

So you can drop down to 10x multiplier and run 10x240 to 10x250 if you have memory that can handle it. Basically you can play around a little with thte multiplier/memory ratio/FSB to get the best RAM performance at a given CPU speed.

The higher the FSB you can run the better.

The biggest issue is trying to find RAM that will run at 250-290FSB @ 1:1 with the CPU.

OCZ PC3700 EB RAM can do 250 but only in single channel (one RAM stick). I can only go that high in Dual Channel if the motherboard would support higher voltage. 3.2 or so, which it doesn't.

Other options are not truly available.

Crucial Bullistix RAM will run stock on this motherboard but apparently it's impossible to overclock it.

So you can get PC4000 RAM from Crucial and you can except 250FSB but beyond that you are out of luck. This might be ok if you can run the CPU @ 10X250 but there is no guarantee.

Also anything except for the EB RAM will run with really poor timings. Most likely 3,4,4,6 at best.

Right now I'm waiting for OCZ to release reviews of their new EL PC4000 Gold Rev2 that runs @ 2.5,3,3,6 on only 2.6v.

This RAM would be increadible for A64 but we have zero information on compatiblity and overclocking at this point.

So far a very similar RAM EL PC3700 Gold Rev 3 ran very well in single channel mode in an A64 system but there is no review yet in dual channel, which they said would be far poorer performance.

Stay tuned.

OCZ has a memory voltage booster available that can increase your voltage to 3.9 without modding the motherboard. Check their website to see if your/his motherboard is compatible. Anand got this board to 290 at 1:1 in memory htt speed so we know it can be done. If the motherboard is compatible with the OCZ voltage booster that is what I am getting for my rig next month

Three problems.

1. The voltage booster isn't rated yet for this motherboard (K8N Neo2 Platinum)

2. We have no clue what so ever as to what RAM Anand used to get to 290 FSB on the above motherboard. All we know is that he used DDR550 RAM. That in itself tells me nothing except that it's PC4400 RAM. So far all PC4400 RAM run with very poor timings.

3. We have no idea what timings were used to get to 290FSB. He could have used some redicilously bad memory timings to get there for all we know.

We need better RAM reviews for A64 before we will know what to buy.

Right now buying anything outside of EB RAM is buying blind. EB is just about the only RAM that is guaranteed to work and will even overclock a little. It needs a lot of juice to overclock well tho.

I would say you would top out at around 2.5GHz. Any further and you would be required to use watercooling or PHase CHange.

 

[demenion]

Friday my ram should be shipped so i'll post my results soon.

The guy who is selling me the 2x512 hynix pc4000 ram said:

"it will do cas 2 up to 250mhz and voltage increase. this is on my asus p4c-800E your board my give different results."

and

"the highest i was able to push the ram was 275 with default timings and voltage" (CL 3-4-4-8)

hopefully i'll try to run it at 250 x 10, and what about the 1:1 ratio? i don't know much about that.

 

[Mullzy]

Sorry if I'm misunderstanding your question about 1:1.

At 1:1, 250HTT is DDR500, 290HTT is DDR580. If your memory won't do more that DDR500 but you can get your board stable between 250 and 290 HTT, you'll have to run your ram at a ratio (i.e. 5:4).

A possible example would be:

CPU: 290 x 8 = 2320Mhz
RAM: 290 @ 5:4 = DDR464

If you look at recent reviews you might notice that the only PC4000+ RAM that ran at the rated speed on A64 was RAM that used Micron chips. Even that couldn't be overclocked. This is in contrast to Intel based CPUs that ran these RAM chips without issues and they even overclocked well.

Not a good sign.

Hynix chips (at least the older ones) ran really well on Intel (no surprise) and piss poor on A64. At least the higher rated ones anyway.

Hynix came out with new chips recently that I mentioned before here. I found out that they are called Hynix IC. I'm still waiting for OCZ to review these chips on A64 motherboards.

Maybe next week.

 

[demenion]

Finally got my system up and running.

Oh yeah, the Zalman HSF fits fine but it is kinda close.

I can't wait to see what I can overclock this to

Take a :camera: in CPU-Z and post it. :thumbsup:

 

[demenion]

well i'm currently running at 2.4 ghz (it ran at 2.5)

(240 x 10.0)

htt is at 3x i believe.. default is 5x?

i really don't know how to oc amd64's.. what exactly should I be going for? i'm sure I am doing it wrong.
the only benchmark program I have right now is cs source stress test and i don't notice any improvement.

anyways cpu-z pic

cpu-z/bios states that that my ram is pc3200.. (i supposely bought pc4000 off a user in the f/s forum) is this just false/inaccurate? or did i really just pay for 3200 ram

You could do htt at 240 and still come below the 1000 that is standard for the 939 boards (i.e. 200 x 5=1000 is standard for htt) 240 x 4 = 960 so it would be fine so I would increase the htt up to a multiplier of 4. We would need you to tell us if the memory is running at 1:1 off the htt you have (240) or in some form of divider such as 5:4. This would tell us what your ram is running at. Check in your bios of run sisandra

 

[demenion]

where can i see my dividers in sisoft sandra? i changed my HTT to 4x

 

[imported_michaelpatrick33]

you can see your dividers in the bios. You could tell by your bandwidth amounts what your approximate memory speeds are. DDR400 on the 939 board should be around 5800-6100 bandwidth at default speeds. That is the baseline.

 

[demenion]

I can't find anything in the bios where it lets you view/adjust the dividers. :X

sisoft memory bandwidth benchmarks reports 5731/5730 MB/s seems a little low?

It is under "Max Memclock". Auto is 1:1.

 

[demenion]

i see values like auto, 100, 133, 166, 200

i left it on 200..

what should I have it on?

 

[Zebo]

100 means HTT x .5
133 means HTT x .665
166 means your HTT x .83
200...(()).x1

That ram is good for 200 up to HTT 250

 

[demenion]

I believe I am at a 1:1 ratio.
10x250 (2.5 ghz)
HTT: 4x
Memory timings: 2.5, 4, 4, 6

Ok my benchies.. do they look normal?

Sisoft Sandra CPU: 11517 3955, 5118
Sisoft Sandra Memory Benchmark: 6017 6003
Doom 3 1024x768 demo1: 42.9 fps
CS Source Stress Test: 95.2 fps

oh yeah, I have a ATI Radeon 9800 Pro.

 

[Zebo]

Pretty sweet... are you at 1T or 2T command rate? I also think 2.5,4,4,10 will serve you better.

Also your Dooms a little low.. run it twice in a row..it should get better the second run.
