300HTT seems to be out of my reach!

[Mekrel]

Hi all,

Recently got my new 939 setup from a 754 setup and I took the OCZ Platinum Rev2's from the old rig and into this.

I couldnt seem to get 270 of of these with the 754 setup but with the older memory controller it wasn't too much of a surprise for that to happen.

So I was hoping to get these sticks (2*512) to really show their worth and go for 300HTT.

The processor, a 3800 venice was bought second hand, and the previous owner ran it at 2.7Ghz on about 1.47 volts. He did show me a CPU-Z verified screenshot of it doing 2.9 (242*12) but I dont think it was stable obviously.

So I think the chip is quite good being able to get to 242HTT on its highest multi?

However, Ive really played around with my memory timings based from kakaroto DDR600 TCCD guide.

I keep falling on DFIs Memtest86+ 1.55, test 6 and Ive managed to get the errors down to 46 from within the hundereds.

The setup to try this was:
3800 Venice 300HTT , 1.45v (maybe I needed more volts through the CPU?)
2*512 OCZ Plats Rev2 1:1 1T (2.8v, seemed to like 2.8 more than 2.9volts) Was running Dual Channel in slots 1 and 3 (yellow banks)
DFI Lanparty NF4 SLI-DR, 6-23 bios
Hiper Type-R 580w PSU

Any ideas as to where I may be falling?

Many thanks

Im not sure but isnt Venice known for having bad mem controller to? Im sure you will find your help here. btw welcome to xtremesystems
(a little bit late for me to say that thou)

[Mekrel]

Thanks for the Welcome

Im not to sure about their mem controllers, Ive seen users hitting 2.7 on 3000 Venices - but I suppose it depends on what batch your chip came from.

Well tried with higher CPU voltage, still no good. Maybe the 704 bios which is suited to TCCD hmm.

[[XC] DragonOrta]

have you tried the orange slots at all?

[Mekrel]

Yes, I did at first being as a NF4 thread at another forum said these usually were more stable, when I had the errors I decided to try the yellow ones and these weilded less errors although, I think I changed some of the memory settings when I did.

I will test again with the less errornous settings and the orange slots.

[tatts]

if its failing memtest then surely the ram is holding you back.
maybe need to slacken back the timings or put a divider on for now and see if it helps
or try 1 stick at a time

[x3ro]

try the sticks seperately.. and see how they do...

[|3ourne]

try the 5.10-3FIX bios. That works the best for me till now. Can you post use a screenshot of your A64 tweaker settings or a pic of your bios settings ?
This is the first im hearing about TCCD liking the yellow slots more. Also try to actively cool them . It helps.

Mekrel,

Try these settings....this will test whether the ram will run 300 first...then you can work on raising the CPU multi so you can find the best balance.

I changes bypass max, 7 is quite agressive here

[Mekrel]

Those options would not boot at all had to reset CMOS

I noticed you had put HTT mutli to auto, but with 300HTT I put it as *3 to stay within the 1000Mhz HTT spec.

I see the plan though to try and take the CPU out of the equation.

[RyderOCZ]

Well, looks like 300 might be out of reach for that pair....try 2.5-4-4 or 3-4-4...it might get you there.

Or just use slightly lower FSB but try 2.5-3-3-x timings.

[Zeus]

Might as well be your memory controller, try 1 stick at a time at 2T command.
If it does ok it has got to be your memcontroler.

Most TCCD will hit DDR 600 at 2,5-4-4-x

[Mekrel]

yeah I pretty sure its the memory controller, but I will try the single stick options.

I can go with lower FSB, will report back when im back from work late tomorrow.

[OV3RCLOCK3R]

how old is your ocz set?

[Mekrel]

Im not sure, I will check the sticks later for that.

At the moment im priming, so far 4 hours stable.

300HTT * 9 but using a 5/6 divider to keep the memory at 250 2.5-3-3-7 , I ran these 2.5-3-3-5 on the old 754 setup, but I swore I read 7 creates better bandwidth somewhere?

I have not tweaked them with the advanced memory timings yet but once I know this is stable I will have a play to get bandwidth as high as possible

Thats with vdimm at 2.8 and temps are brilliant, the CPU hasnt even gone above 43 degrees yet with processor using full priority, chipset sticking around 41 degrees with about 1.7 volts going through it. Chipset used to idle higher than that before reseating it with some AS5 and thinner pressure pads.

Thanks for the help, ill keep an eye out on getting my hands on some proven 300HTT+ sticks so I know if it was the memory controller or the ram itself.

I have the feeling its the actual sticks though.

Cheers

i have a problems with my g.skill 4400le and i have spent weeks playing with it one thing about my sticks is that more often they react better with tighter timmings than loose so try what i boldeded one by one and see if memtest errors decrease, also even if mt passes tons of loops doesnt mean it will be stable in windows since with some settings i can mt all night but i get bsods in win with whaterer multy or voltage, doesnt cost to try (except time
