3stars Posted May 15, 2006 Posted May 15, 2006 anything over 2.9ish will need active cooling if there hot to the touch well.............. i think you shold check out the overclocking guide as you timeings are pretty loose for such a small o/c also check these two links out: to find out what ic's you've got http://forums.vr-zone.com/showthread.php?t=47615 to find out what they can do http://www.xtremesystems.org/forums/showthread.php?t=50010 opps think i got the links the wrong way round Share this post Link to post Share on other sites More sharing options...
Johnkam Posted May 15, 2006 Posted May 15, 2006 By active cooling do u mean placing like 2x80mm fans in front of the ram chips, will this be sufficent??? so i can go to 2.9v pretty safley>>> Share this post Link to post Share on other sites More sharing options...
ICON57 Posted May 15, 2006 Posted May 15, 2006 your geil ultraX is tccd (nice ram) avg volts are 2.7...you can go as high as 2.96....tops Share this post Link to post Share on other sites More sharing options...
Johnkam Posted May 15, 2006 Posted May 15, 2006 its tccd???? because untill this point i was thiking that they are BH5 chips and using BH5 settings for them.... So do u think its possible running a 1:1 divider @ 2900mhz??? Share this post Link to post Share on other sites More sharing options...
3stars Posted May 15, 2006 Posted May 15, 2006 read the oc guide find the max for your cpu then the max for your ram then get them together the guide is much more detailed Share this post Link to post Share on other sites More sharing options...
Johnkam Posted May 15, 2006 Posted May 15, 2006 how can i check if my memory is tccd or bh5??? is there any way?? Share this post Link to post Share on other sites More sharing options...
ncsa Posted May 16, 2006 Posted May 16, 2006 If these are PC3200 Ultra-X with PN-1243 on the back then they are likely to be UTT chips. I have a set of these and can now run them at around 250 2-2-2-5 BUT need up to 3.35v. It did take a lot of burn-in using Memtest. Check your model and part number plus the date when purchased.

3stars Posted May 16, 2006 Posted May 16, 2006 or void your warranty and remove the heat spreader the numbers on the ic should give you a glue then check what they can do in the guide i posted a link to above Share this post Link to post Share on other sites More sharing options...
ICON57 Posted May 16, 2006 Posted May 16, 2006 i had a pair of geil ultra X pc4400...they were tccd the other flavor they had were pc3200, afaik...both ultraX rams were tccd when they first came out.....bout a year ago....they might have reviesed the ic's they were using while in production... the pc3200 could run some tight timings of 2.2.2.5 but avg was 215fsb, after that you needed to loosen the timings...some ran as high as 275fsb 2.5.7.4.4.....if yours are acting the same way, i would guess tccd ic's...imho Share this post Link to post Share on other sites More sharing options...
Johnkam Posted May 16, 2006 Posted May 16, 2006 with a 1:1 divider i cant go past 2400 on my opteron with stock settings... will pull a stick out and see what it says on the stickers, i got these around 2 weeks ago... burning in??? so ur saying the better burnt in they are the better they will oc?

ncsa Posted May 16, 2006 Posted May 16, 2006 If these are PC3200 AND UTT chips they could do better. Since they are new if is very unlikey they will be TCCD as they stopped using those chips in the PC3200 modules nearly 18mths ago. Look at the label and tell us what the PN ...
