GeIL Black Dragon PC-8500's

post #1 of 5
Thread Starter 
So, I have some GeIL Black Dragon PC-8500's.

First question is, are they still using elpida for these chips? coz the IC list suggests so:
http://www.overclock.net/intel-memor...-ic-chips.html
at some point I must stop being lazy and actually have a look

Secondly, because of the way my memory dividers are worked out on the gigabyte with my current OC, I have the option of DDR2-1000 or DDR2-1200.

DD2-1000 obviously works fine with rated 5-5-5-18 timings. I managed a boot at DDR2-1200 with 5-5-5-18 @ 2.2V (rated for up to 2.4V):


but it wasn't memtest stable, errors almost straight away. I might try upping the voltage..not sure if that will help though.

I want to be running at 1200MHz, I figure I can get £55 for these chips on e-bay since memoryc.com is selling em for £71:
http://www.memoryc.com/computermemor...dragonkit.html

and then possibly getting some ballistix PC-8500's? I've been a big fan of ballistix since I had a pair or PC5300's that I got a 1080MHz boot from! completely stable at 960MHz. I understand the PC6400's have been given single sided IC's, but the 8500's are ok still?

edit: jut spoke to a crucial rep. All ballistix will be shipping with single sided IC's for the forseeable future death of great RAM.

Are those ICs bare or is there a spreader on them? Some of the Black Dragons supposedly have the same IC that my Kingstons have. I could probably tell you from a photo even.

I know I'm going to get flamed for the following...but here goes anyway (dons Nomex suit)....

I'll put my Elpida E5108AJBG 8E-E sticks up against Micron D9G(take your pick) sticks any day. They are at least comperable and (dare I say it?....I do!...) SUPERIOR, if only for the fact that the D9s have a tendancy to die between 2.0-2.2V after a few months.

I wouldnt go that far. The early D9 chips didnt die very easily and depending on what pcb they were put could handle some volts. My cellshocks are still kicking just fine and got 2.4v thru them for well over 6 months. Varies by chip and ram maker. Old D9GKX will kill just about anything ddr2 on the marke tthen and now. Very nicely picked D9gmh older versions hold most if not all the ddr2 ram records along with the kx guys.

But your ram is still nice and does its job. I just wouldnt call them superior in anyway,

Ontopic I am interested to know if you can make the mhz stable at 1200 with a small bumb in voltage or maybe try raising the vmch a bit which very well may work.

bit of an update then guys, I went soulja boy on teh voltz last night to 2.4v, no joy
So I tried 2.4v, 6-6-6-18, still errors (not as many but still).
As one of the reps says on the GeIL USA support forums, black dragons are built for stability..not overclocking. They are very good RAM sticks but not as exciting as the red eyes on the RAM suggest

So anyway, a guy on another forum has agreed to buy em off me, and I found a storming deal last night. I was stressing all day over which RAM to get coz I wanted guaranteed decent double side Microns..
ballistix is a no go area, as I said above, all single sided from now on.
Buffalo firestix just aren't available in the UK full stop, the buffalo sales rep agreed lol.
OCZ and Corsair have stopped using Microns in 1066 Reapers and Dominators

So just before I went to bed I thought I'd check ocuk. They've got a memory clearance atm and I found these two:
http://www.overclockers.co.uk/showpr...id=685&subcat=
http://www.overclockers.co.uk/showpr...id=685&subcat=

for all the good people in the US of A, both these RAM brands are fricken rare in the UK, and I've never seen OCUK stock them before! Only one other place does the team xtreems and they are £70, the very few places that stock cellshocks have em for £70 too!! £35 for 2GB of both these brands is too good an opportunity

I went for the Cellshocks coz of the 8 layer PCB, and I figure since Cellshock are a german company, should any Micron issues arise RMA will be easier.

Will they reach 1200MHz? maybe, but I'm sure they will do tighter timings than the black dragons at 1000MHz if not.

I think I can do 1200 and stay under 2.3V for sure. These seem to really like low voltage. While I have not been 1200 stable I have made some progress by getting as far as the XP login @2.20V.

I've been taking advice from Tony of OCZ fame at XS. We both think that my particular problems getting higher are due to clock jitter and skew. Tony thinks that advancing the Dram Skew 100-200pS should do the trick to account for jitter, additionally I probably should set DRAM_REF to -10mV to decrease the skew.

Edit forgot to mention......I could raise tRFC above 35 or 40 too, the fact that tRFC 35 posted @1200 posted simply amazed me to begin with.
Also one category those D9s win is tight timings even at high clocks. CAS3 is no prob for 800 and probably to 950, I've seen D9s pull off CAS4 @1200 w/2.5V.

Elpida E5108AJBG -1J-E (1J-E was an early mask for 6E-E and 8E-E grade engineering samples) ICs running 1260MHz on low voltage. Page 2 of thread, last post.
