i disagree with velvet.

Not many chips run 800Mhz CL4, and few run 1066 at anything less than 5-5-5-15.

Dont run above 2.0v without airflow over the ram, especially with 4 sticks... they will slowly heat up and cause you to BSOD after several hours (but will pass every stress test you throw at it, since the heat dissipates when you leave it off for a while between tests)


that said, you *have* patriot 1066Mhz ram... so you should be able to up to 1066Mhz (likely at 2.1v, and you may need to bump NB volts like i have to)

lol? i never had a kit or single stick that wasnt able to do 800 mhz cl4, no matter if specced for or not (everything below ddr 800 maybe... but not 800 cl5 ram). may be so, because i never used old ddr2, just never versions of ddr2.
mine never failed running even at 900 mhz cl 4, or up until 950, where it began that modules needed cl5
i agree tho, that 1066 with cl4 are pretty difficult to achieve, and you need the modules for it. D9 are probably one of the few chips, that in some cases could even run up to 1200 4-4-4-12 stable
but again, i would say, that up until 2.2v are safe, given that the ram has functional heatspreaders (clean ram or cosmetic spreaders with little use, may be at their max with 2.0 and no active cooling)
everything higher surely should be cooled, that is in fact a truth.

as mussels said, 1066 should be easily achievable regarding that that is its stock speed ;-) but it can fail, if youre very unlucky and your ram is a monday model (happens,but is rare), or semi-incompatible to your board.

 

[TheMailMan78]

to be true, thats a worse than stock setting with ddr2! (like mussels said, JEDEC timings... they are slower than stock timings of your ram in 90% of the cases.
if you would like to change that, i can recommend you 800mhz 4-4-4-12 or 1066 mhz 5-5-5-15. voltages shouldnt be above 2.4 for 24/7 abd even that only with good cooling.
Most modules should be able to hit the 1066, even if they are not specced for that

Remember I am runnin' 8 gigs of DDR2. 800Mhz is max due to the memory controller. If I lower it to 4 gigs I can run 5-5-5-12 1066 all day on stock voltage. I've done it. My question is should I lower my timings or leave well enough alone?

The memory controller on your x6 is perfectly capable of running your RAM better at better timings. It's either a limitation of your RAM or your motherboard.

 

[cdawall]

1066 cas 5 is terrible even for 2x2gb I have had crucial reds back in the day running 1260+ cas6-5-6-16 on an rb-c1 phenom 2

 

[brandonwh64]

my hynix sticks run 1066 with 6-6-6-16 @ 1.96V, the board wont boot under that.

 

[Chicken Patty]

Hey Ben, I think your issue is not the IMC. It's possible but, I would have to agree with erocker on this. Just my two cents.

 

[fullinfusion]

I think his issue is the mobo to be truthful.... mixing an am3 cpu with an older ddr2 board don't really play that nice together, plus the clocks your running... 1.47v you gotta be shitting me

Id say time to move up MMan

 

[crazyeyesreaper]

was gonna wait for the water stuff to arrive but ive grown impatient as such..... my overclocking of my 965be will begin soon enough im late to the AM3 party but lets see what this machines got with just air cooling and keeping it under 60'c full load

shooting for 3800cpu 2600nb 1450 ram at 7-7-7 21 1T

not poking at anyone here if it seems that way just the pc is setting next to me and shes to quiet need overclock her and make her scream

You both are wrong on this one.

800MHz is MAX for any board and ram combo once you hit 8gigs. My question is the timings.

 

[cadaveca]

LoL. That doesn't prove anything...just the SUPPORTED max..in other words, if you don't get that, you can RMA. Those numebrs are for WARRANTY ISSUES only.


The fact you overclock specifically states you don't care about that..as the max SUPPORTED speed of your cpu was what it was sold as...not what you are running it as....the supported max for your cpu is 3.2ghz, and you are running 3.9ghz...

even better, if you actually read the info you link, it says for M2 and M3 boards, not M4 boards.

Well prove it man. Show me how to get 8gigs of DDR2 RAM to run at 1066.

 

[cadaveca]

Read my edit, and actually read the info you link before stating it as fact...because that says for SPECIFIC boards...

CROSSHAIR II FORMULA
M2A74-AM
M2N-CM DVI
M3A
M3A32-MVP DELUXE
M3A32-MVP DELUXE/WiFi-AP
M3A76-CM
M3A78
M3A78 PRO
M3A78-CM
M3A78-EH
M3A78-EM

You aren't running any of those boards, so it doesn't apply.

Now we can add in that it says AM2+ cpus, not AM3 cpus....

 

[TheMailMan78]

So what? Up the voltage? I ask because I run 1066 on 4gigs all day. Its just when I hit 8 gigs do things go south. Honestly I'm about to say F@#k it and run 4 gigs.

 

[cadaveca]

Yeah, most likely IMC volts.

Or you can also try lower NB speed...start with 2000, and see how high you can get with just 2000NB, and once you get 1066 stable, then up NB, one multi at a time. If NB gets stuck at 2000, then you can blame the IMC, assuming that the bios for your board is perfect...and I know for a fact thuban support is sketchy at best at this point with your board. ALL ddr2 boards are gonna have issues with Thuban...you're truly lucky to even have that cpu working with DDR2.


I'm not suppose to be able to run 8GB @ 1600mhz either, but I am, on 955...Thuban has a better memory contoller, so if you are having any issues, it truly is because of the board/board bios.

EDIT, btw, if you have any further doubt...check the Crosshair4 2000mhz QVL...4 2GB sticks @ 2000mhz is supported...

I'm already running at 2000Mhz. The only thing OC on my board is the multi in the CPU.

 

[cadaveca]

Then I'd blame board/bios, rather than the cpu itself. according to the "specs", you should be running 2400mhz NB...can you?

I myself have exact opposite...with 4GB, I'm not stable...added in the extra 4GB and stablity was there, and I got to drop cpu-volts as well as cpuNB-volts, too...


I know that in my case, that's because of the bios. The newest beta for my board seems to have fixed that, and 4GB is pretty good now too...

 

[Chicken Patty]

Well prove it man. Show me how to get 8gigs of DDR2 RAM to run at 1066.

My buddy has my old Phenom II 940 and 790GX board from DFI. DDR2 1066 all day everyday 4x2GB. He simply set it in the BIOS and booted. His is advertised higher than 1066 though, it's 11xx something. However it wouldn't boot at other available boot settings. 1066 is the highest he can boot.

I don't know if your problem is board or not, it sounds like it to me. However, it could be the most minimal thing, one particular timing/voltage. Just play with it, I don't know how long you have been, but keep trying bro, you never know if that's all it'll take.

 

[Velvet Wafer]

sounds like your board is highly incapable of OCing in common,or at least, for the thuban there is only a semi-compability. the dividers are really important for OCing...im telling you no shit. do you really,really believe it isnt the boards fault?

So what do you think? 4gigs at 1066 or 8gigs at 800?

I'm not arguing. I'm trying to find out. It bugs the hell out of me.

 

[fullinfusion]

what cpu you running? 1090T?

the c2 chips (955-965) only support 2 sticks @ 1066mhz...
c3 you can run 4 sticks...

1090T EO revision can run 2000mhz up to 16gb....

Mail man dump the old mobo and get a board that was made for your x6

That way you wont be rant-in an raving about why cant my memory run at *****

does that board have a MEM OK button? if so push it and see what happens and let us know.

8 @ 800 with low timings, 4.4.4.12.20 if it can handle it is faster than 5.5.5. @1066mhz

 

[TheMailMan78]

Photoshop is very sensitive to RAM settings. If possible I try not and mess with RAM timings.

now, for that statement i want proof now! do you have some comparance benchies?

I cant lol, I tossed the ol tech out the window a while ago.

im running 1600+mhz 7.7.6.15.25 1T atm and 6.6.6. when bumping the volts up , and next week going to be running some sweet Trident 2000MHz sticks... Ill show ya then

 

[fullinfusion]

I have some DDR3 1600mhz Plats F/S if anybody is interested...

@ mail man.... show us a screenie of your cpuid memory SPD tab please with all sticks installed.
