well, i also gotta say that it was under load in memtest.
Hi
This is ny first post here on XtremeSystems.
I have also G-Skill ram, i got them because my 2x512mb OCZ4000 VX broke down, and then i thought that 2x1GB could be fun.
So i have been playing arround with these ram, i know that my max on my cpu is 2921Mhz, so the drill was to get so close to that as i could.
This is what i have done so far...
Btw if you have son´me ideas to better my oc please say so;-)

3-4-3-8 that is nice
do u try 3-4-4-8 with higher FSB?

OK I take back my previous comment... I just did a pc overhall adding a GPU waterblock, Video vmod, an active cooling on my ram and PWMIC. So I figured I would check and see if there was an improvement with the ram and I guess I didn't have enough air flow over the ram before. Still testing but now I'm able to at least get 1:1 up to 270. Try and go 275 and I get a system corruption error. So I'm going to settle with a divider for now. Wish I could figure it our so I could try for 285.

Try lowering the V on the ram. I am down to 2.5 and I am still able to hit 280 @ 1/01. Otherwise our voltages are more or less the same. I will take a screen for you when I get home. My chipset temp is lower though. Try modding the chipset fan, it makes a noticeable difference, that may do the trick for you.
Did anyone tried to peek sideways on the sticks? There is almost no contact beteween the thermal tape and the chips, i would say a 1/4 of contact surface. Just look at them against a light or white wall. I still don't have my system running but i don't know if i should remove the heatspreaders. Maybe after i verify if they can function just in case i need the warranty. I think for people trying to overclocking them to the max, pointing a fan with the heatspreaders on the sticks has limited impact.
UCCC 2GBHZ has very low temp, not really needs a fan. but it is always a good idea to have one :)
I tell you, they were at 60ºC at least, at only 2.61v. :stick:Quote:

TCCD? BH5,BH6,VX,UTT?
sry if its obvious
They are UCCC ;)
Maybe not at stock speeds... But you surely have noticed The thermal tape doesn't even cover half of the chips, maybe a third... The heatsink acts more like a cage in that matter... I can see the gap beteween the aluminium and the chips.Quote:

Good question.. I have to tear down later this week when my new processor arrives so I will take advantage of that and give them a closer inspection. Honestly though, mine do not run hot. I can tell you at 2.5V they don't really feel warm to the touch. I have checked on occasion as I am really big on having my components run cool. Although I do not have a fan blowing on the ram directly, I have a CM Stacker case with the crossflow fan so there is some air being blown on them.. pics included.
If you are not familiar with the set up on a CM Stacker, the crossflow fan is the black object that runs the length of the motherboard just to the right of the motherboard. It takes outside air and blows it over the components. I normally run the fan on medium speed, this has proven to give me a 2~4c drop in temps on the PWMIC.. the chipset has its own cooling so there is not drop in temps there that I have noticed when checking MBM5 or Smartguardian. I am sure the ram benefits some as air is being blown over them but I really do not monitor ram temps as I am undervolting them as it is plus I have not noticed they get warm.

Perhaps because you're not really feeling them but the aluminium heatspreader that is not touching the RAM chip because it only has a stripe of tape (2mm wide) on the lower part of the stick near the slot edge. If your sticks are equal to mine (since their are the same product) you'll see (without removing nothing but the stick from the motherboard), that the there is almost no contact with them. Now that i'm thinking, even the thermal probes that come with my case fit in there!!!, i can (eventually) test the temperatures (the real temperatures, not the temperature of the aluminium heatspreaders that do not make contact with the chips!!)Quote:

look by the side that the gets secured by those clippers on the motherboard ram slots, while pointing them at a wall or light.
PS: I look at your case setting and i envy you, i want to put a 120mm fan on top of the ram, if you consider the cpu cooler i have it's IMPOSSIBLE, you on the other way, only have that neat water block, you could put a fan directly over the ram, instead of relying just on the mild airflow that you fan makes by blowing air inside the case as a hole.
what i want to try is to have no intake fans, just fans driectly over the components and direct vent to the ouside, thiis alone would create lack of pressure inside the case making air entering by the holes in other places. This way i have the air pressure directly over the components. I don't know if i sound clear.
Sorry if this hijacks the thread about Gsksill PC4000 Hz... It was dormant anyway :D
PS2: I've noted your using a Beta Bios, I'm still deciding what Bios will i use. The 623-3 or the 704-2BT. I've seen people not doing very well mixing the 704-2BT and gskill memories ,BSODs and stuff. Still figuring it out. You seem have the highest overclock using it tought.
I need to clear on the "Tape" thing!!!
cover 1/3, 1/2 or full cover, more coverage will result worse temp increase. we test direct from chip not from heatspreader. when IC cover 1/3, it still have so air direct flow through between IC and heatspreader. that is the best we can do with heatspreader. full cover and 1/3 or 1/5 or even 1/10 is "same price" for our cost! like the heatspreader, the cost of that is very very low but why we need it? it is for the "eyes candy". G.skill always does temp test before we give out our product. that why we were the only company didn't use heatspreader for TCCD such expensive IC.
Soooo.. Can we take the heat spreaders off to get better air flow over the chips... I took mine out to put my 1gig PC4400 Gskill TCCD sets back in for some testing and I see what lusonico is talking about...
once you take it out = No warrenty
only $217 at the egg now. great price, mine should get here early next week. hopefully it wont cause my comp to bsod all over the place like the zx it will replace
After all the issues with my last modules I wasnt expecting such immediate results..booted first time with the N4D702-3 (oskar wu beta) bios! I ran some early tests and found it was stable@200x11. Upping the fsb to 250 need some adjustments though. In the bios I had to set the dram signal strength to 1, and the read preamble to 5. This was then tested in memtest, test 5 and looped with no errors for half an hour. Upping the fsb even more I hit a ceiling at 285!!! At this point I found out the these modules actually like more voltage, I got 100+ errors in memtest test 5 @2.5v, but at 2.75v I got only 10. Id like to say at this point that the modules dont really get hot just barely warm to the touch, even with more volts. 285 was not stable though and after much testing Ive settled on 271x10 @2.75v 3.4.4.8. Ive tried to get the TRCD and TRP to 3 but its a no go, as is the CAS to 2.5, but that would only be useful at 200 or 250, not max oc. The settings Ive found that effected the stability the most where voltage, TREF, Read Preamble and Drive strength. Ive seen people get to 280+ with just 2.5v but mine dont like that.
Im amazed at the difference between these and my old corsair dimms, not only do they do a higher fsb but theyre alot easier to tweak - and of course theyre twice the capacity!

You had problems with an earlier set?
^^ Nice work, are you running that at 1/01 1T or are you using a divider? I just received my 3500+ so if I can reach 280 like I did before on the x11.. I would be breaching 3000 with that CPU. I have my fingers crossed that the memory controller on this chip is as good as the 3000+ I just retired.
So far, with the new CPU I have reached 245*11 without any changes to the memory settings other than setting it to 1/01 CPC Enable and 3-4-8-4.. also I lowered them to 2.5V. I tried for 250 this morning before heading off to work but it did not boot, I am also running at stock voltage on the CPU so I am sure I need to raise that to compensate for the higher OC. I will post results of course as I get them.
sorry didnt make myself very clear..my last set where 1gb corsair xms4400, didnt like my dfi board at all:(Quote:

yes theyre 1:1 and 1T. Its only taken around 6 hours to get them to max oc, wheras my old corsair dimms took over 2 weeks! much easier to tweak.Quote:
