Running BH-5 and CH-5 at the same time...

[hollywood]

One last question before heading to bed:

I built a machine for a customer about 2 months ago and used Corsair 2x256 PC3200 LLPT BH-5 (This was my "old" ram). He now wants to upgrade to a gig of memory. Of course I want to purchase an exact match...but I can't as the newer Corsair 2x256 PC3200 LLPT is CH-5. The native SPD timings are off between the two of course. So here's my question:

As long as I set the timings to CL2, 2, 2, 6 in the BIOS or even CL2,3,3,6; will the ram play nice together??? This is all at stock speeds of course, as OCing isn't even in this guys vocabulary.

I think it will be ok as long as I force conservative timings in the BIOS. But I just wanted to ask in case there were and system stability horror stories from running BH5 and CH5 together.

Gnite.

I don't see a problem at stock speeds on an AMD system, but I guess some mobos could be more fickle than others. I do have 256MB of BH-5 ValueRAM PC2700 and 256MB of some junky HyperX CH-5 (think it was the 'A' type PC3200, not sure) in my K7VTA3 (KT333) rig, but it's only running at stock 133FSB.

I would venture that the main thing will be if the CH5 will run CL 2.

I'd say it would work. I run a 256MB kingston and a 512MB twinMOS bought 6 months apart, one in Ireland one in Malaysia in Dual channel with no probs. I've used these in two boards with no isuues and tight timings. I know its only DDR333 and not bh-5 but from my experience I think people's fear of running different RAM's in the same board is the result of marketing rather than fact.

I think you should upgrade him to the gig of ram and sell the old BH5 here:D Although as long as your latency and speed settings are useable on all the modules it would be just fine;)

I forgot to say what he was running: 3.0C on ABIT AI7 at all stock speeds.

Yeah...I think as long as I specify slack SPD timings he'll be fine, as selling the BH5 and buying a gig of whatever is too much of a hassle.

Well im running 2xBH-5 + 1xCH-5 here. All Corsair modules.

Timings 11-2-2-2-13-15-2

Im good to go at 230mhz with all three sticks. The overclcok is limited though. The CH-5 by itself can hit over 240mhz, the same can be said for the BH-5's when paired together.

But default settings should be ok
