can't reach hight fsb with DFI Lanparty UT 250Gb

[Methodlol]

Hello all,

as writen in the title, I can't go above 240FSB with my mobo. After 240, the mobo won't pass the "verifying dmi pool data" step. As I read that some review reached 300FSB, I guessed I did something wrong. May you help me please?

CPU is a 3200+ Newcastle CG and ma memory ADATA Vitesta PC4000

thanks

try lowering your HTT multiplyer to 3x, or try and raise the chipset voltage to 1.7 or 1.8. When i was pushing my fsb over 250 i had to change my chipset voltage and my HTT multiplyer..

 

[Methodlol]

In fact I solved the problem. My SATA HD was connected on SATA 1&2 and to reach high FSB it has to be connected on SATA 3&4

I hope it'll help other people

Also don't expect much over 250 with 2 DIMMS. Plus your RAM may not want to go much past PC4000, which is a FSB of 250 with a 1:1.

thanks, i'll keep that in mind when i try out the one i bought.

Hey Methodlol what temerature reading you getting with that DFI LANPARTY UT nF3 250GB?
I have the exact same board and CPU as you and im getting really high temperatures.

I ran 260 FSB 1:1 divider@cas2.5-3-3-7 with OCZ platinum rev2.

here is what I found out,
The ONLY stable VDIMM is 2.9. Don't even try 3 or 3.1. It's not stable, not even if you raise the rails on psu to give it more juice.

I was running 8x260, and 9x260 with stock volt on vcore.
(raising the vcore wouldn't only make the computer boot under load because of lack of cooling on cpu)

the memory on 2.9 volts won't do any more than 230-235. boot yes, but burn in and other benches would reboot it if any over that.

So what do I have? I have chips that are rock stable on 225 and 220 fsb with tight timings. I have a cpu that can do 2.3 ghz and still be stable and cool.

I tried 220x10.5 and 225x10, neither are stable. under load the frickn thing just crashes. I'm running tight timings 2-2-2-11. as 11 is best for gaming and 3dmark.


I swapped the SATA ports and that helped me alot.
But my conclusion is that it doesn't work well together?

you guys have any tips or hints?

Someone explain to me how this HTT Multiplyer and 1:1 stuff works before I go insane!

 

[Shimmishim]

HTT is just the A64 terminology for FSB...

it's HTT because there is no northbridge that controls the mem and cpu.. it is all located on the physical processor now..

1:1 means running your ram and HTT or fsb in synch.. so 230 htt = 230 htt

when people say things like 5:6 that means.. running a htt of 240 but ram is at 200

as for the issue with the SATA ports... it's been a known issue now that the external SATA chip controller is wack and won't let you get high htt's...

but with the internal one which is ports 3 and 4 you will... there is a thread about this over at xtremesystems.org

as for 11 giving the best performance for gaming and 3dmark... i think it's more than just those programs but i could be wrong...

hehe, didn't dare to say it was all apps. I just know for sure it works on games and 3dmark

lol, it is a bit confusing, isn't it? not sure if i'll make it better or worse, but i'll take a stab at it

the reason it's so confusing is partly because the term "htt" can refer to 2 different things. in most reviews/articles it's used to refer to amd's HyperTransport Technology (term describing the data interconects between the cpu & mb in a64 architecutre), however in the context of overclocking, the term actually refers to the clock generator. the thing about overclocking an a64 is to that you're not just overclocking the cpu and memory, but also the HyperTransport link (similar in "spirit" to the term FSB) and the clock generator (HTT).

HyperTransport = HTT x HT multiplier.

the 1:1 stuff refers to memory, and gets a bit more complicated... but it refers to the divider which determines the final memory speed, generally seen in the bios as 100, 166, 133, and 100 (which are ratios of 200 - 1:1, 5:6, 2:3, and 1:2).

If I had a HTT of 250 and my ram was at 210 I'd have a divider of something..... Ideally though what your saying is you want the HTT Speed the RAM Speed the same? As I understand Hypertransport is defauted at 200x5, which is 1Ghz effectively 2Ghz bothways. So I'd want DDR400 then? If I wanted a HT of 233 I'd want DDR433 correct? I would assume the reason why the S-ATA isnt working is because its on the PCI Bus which now isnt a exact 66.6Mhz.... Since you changed the HTT or whatever... I think

Might want to check this out.

I have high temps myself on this board, just haven't had the chance to update bios.

yes.. if your htt is 250 and ram is 210 then you are using a divider...

well in the case of amd's... amd isn't bandwidth starved such as the p4's... p4's are very dependent on fsb's...

and then there's teh issue of high fsb's and loose timings vs. lower fsb's and tighter timings...

and 233 = ddr466

and yes yo uare correct about the pci bus frequency not being 66.7... it may not be locked or just have issuews above 240

Now the question is what kind of ram should I buy?

 

[Shimmishim]

ocz pc3200 plat rev 2 or

the new gskill look promising as well from anand's recent memory review

 

[Tab]

Thanks, I assume that if I bought really low latency DRR 400 I'd be able to loosen the timing and make it higher speed, or if I bought something with loose timings and a high speed I could lower the speed and tighten the timings... Anyway, I assume things will stay the same with the Crush Chipset that is coming out? Memory ratio things...right...

 

[teddy07x]

nah, I figured a way around. some dandy setttings. lame ass LDT and changing the memory bank.
240@1:1 now with cas 2-2-2-5

please explain the LDT settings if you can. i left everything on auto last night after putting it together and tried it out with my mushkin basic pc3200 2x512. i upped the fsb to 220 and the memory had problem even at 3.1 volt vdimm on channel 1 ( i used 1 and 3) is there any ways to get around that? where is the HTT multiplier? is there a guide somewhere that explain these setting? the manual is lacking compared to the Asus board i have.

Well... here we go.

LDT is basicly the thing that multiplies the FrontSideBus aka. HTT.
if you run 250FSB with 5x (default) LDT you'd have a speed of 1000mhz FSB.
Intel has 4x as default. with AMD 64 you can adjust it lower.

if you want 220-230 FSB and say 10x multiplier you'd have an effective CPU speed of 2.2 or 2.3 ghz.
now, you want to keep the system stable, so you LOWER the LDT to 4x. the 220 or 230FSB x 4 =880 or 920 FrontSideBus (FSB)

Keep in mind, that's why AMD has LDT AND HTT. Instead of just FSB like intel does. you can actually lower or raise the effective FSB.
An INTEL P4 running 250mhz would have 1000mhz Effective FrontSizeBus speed.

hope this clearified something for ya.

And you don't need 3.1 volts to run Mushkin 3200 mem on 230 fsb. I think they are stable on 2.9. maybe even 2.8.

 

[Maximus96]

maybe its not the memory failing then. one stick gave errors a few minutes into memtest. i will try to play with the settings tonight when i get home. thanks for your help.

What cpu are you running?
I've got a 3200+ DTR clawhammer, so I can't go beyond 10x.
With my Mushkin level II I can run tight timmings (2,2,2,5) and 1:1, but I hit a wall with the fsb at 235 (235 stable, beyond that no.)
With OCZ Plat rev2 I'm running 260 fsb stable, but I have to run 9:10, w/ 2.5,3,3,10 timings and relaxed LDT. I get a bit better bandwidth that way, but most of the gain from the higher frequency is given back in the relaxed ram timings.

And you're right on about the dimm voltage. Beyond 2.9 on the Mushkin, or 2.8 on the OCZ, things become unstable sooner.

I think I read in another forum where the LDT number doesn't really effect performance that much. So set it low for stability, and don't worry about it for tweaking.

 

[teddy07x]

FSB doesn't give you much of an increase, nor does LDT.
tweak the memory. that gives you the most. at the most, 1000 3dmark points, and alot of frames.

no need to run 8x260. 10x230 should be fine. if your cpu can do more, then wait until DFI puts out a new BIOS. so you can run it stable on 3volts. should get you to 240
