What do you do when your memory out-preforms the Front Side Bus?
Currently running at a 9:10 with Front Side Bus at 450 (450X4=1800) memory at 500 (1000) 5-5-5-15 2T? 1800:2000 = 9:10
Man this crucial ballistix far outweighs the previous GEIL by means and bounds. But the GEIL got me to as far as I could go due to the FSB not working at more than 1950.
I can't seem to cox anything else out of my FSB or is it NBCC?
mine maxes out at 1000mhz, and I'm pretty happy about that. I know John has some really good stuff now.
Clearly the Crucial Ballistix AA804 (PC2 6400) are too much memory for this board. I guess I should have thought about it a little more. Well, there is always my AMD system or the option to sell.
Going back to my GEIL which I bought for my AMD system and still waiting on Corsair for an RMA on my XMS2's.
Too much memory you say?! HA, the ability to run them at a higher speed with tighter timings is what makes them great! Pretty sure not using the 1:1 ratio or synced or whatever isn't gonna hurt your performance much. Could someone do a quick test at 1:1 and then at your max ram speed with the same timings to see which is faster in super pi or something? Sorry if I came off harsh, but I think the ballistix are a good value for the people that want quality ram gauranteed to have micron under the hood.
I would not have made such a bold statement unless I had run several test using SuperPI. With the GEIL I am stuck at 820 4-4-4-12-2T but I can clock to 1950 on the CPU and I get about 15.754 sec for 1M. With the Crucial Ballistix I can go to 1000 at 4-4-4-12 2T and again 1950 on the FSB for 3900 with a SuperPi of 15.749. Unfortunately I can not run 1:1 at this ratio so I am stuck at 2T. When I do lower the mem so that I can run in 1T say 950 with a FSB of 1926 the loss of dropping to 950 instead of 1000 has no effect on SuperPi but THERE IS NOT ANY GAIN EITHER GOINT TO 1T because it is limited by the FSB and not the memory. Hence, the memory speed is more than the FSB speed which makes the memory less effective with this board than the GEIL has been. Even if I did gain an additional 1 second on SuperPi, it does not warrant the extra $70 for the memory.
I was hoping that the GEIL memory was limiting the FSB and the Ballistix would give me more FSB leverage but that is not the case in my setup.
Does anyone have a higher FSB than 1950 for 3900 with an E6400 and P5N-E SLI on Air?
If you do, please chime in and let me know how you broke the 1950 barrier that I have found with three different sets of memory (Geil GX22GB6400UDC 4-4-4-12 at 2.1v to 2.3v, Corsair TwinX CM2X1024-6400 XMS2 5-5-5-12 at 1.9v, or the Crucial Ballistix AA804.16FB3 4-4-4-12 1T at 2.2v) that I have used with the same Motherboard and CPU.
The Crucial Ballistix are great and I did go after them for the Micron chips and I am glad that I did but they in no way gave me a boost of more that .05 sec in math calculations and that is what computing is all about, the ON/OFF position of the switch.
