Regadless of the RAM 4 or 8 GB the strap doesn't matter, its about the memory type not the size of the memory.

It's not good, cause hynix 4Gb is AJR memory, but 8Gb - MJR memory. Both types needs it's own straps.

I bolded the 4 GB cards the first set is Elpida and the second set is Hynix. As you can see the clock speeds turned down in whole group still gets above 32 Mhs. If i run the cards individually it'll go and hold 33/34 Mhs at 2200 and 2250.

I'm talking only about hynix memory. I just know that straps from 4Gb AJR memory didn't work properly on 8GB MJR memory.
Maybe Claymore make different straps on 4 and 8Gb cards with hynix memory. I didn't know. Just pointed...

On my 8Gb hynix memory cards no one strap from Claymore miner didn't give high speed with stability. Even 1st strap can hang all system, but speed is low. Good speed on 3-4 straps, but no stability at all.

Strap 1 on hynix should be the most stable, check your frequency on the memory setting. rather than using gpuz i run strap on 1 to find out the memory cause its faster not sure why you'd be having problems crashing unless you're pushing it too hard. If its the memory on the cards giving you an issue, remember Strap 4 is the higher intensity for Strap 1. It might? run better with that for some reason?

Make sure to watch your voltages. and DO NOT run Afterburner or wattman after setting the strap. Set the speed in the command line. Changing the speeds while Claymore is running you will enduce crashing as its not designed to work with on the fly like that. Its designed for you to change the straps and frequencies without rebooting, not without shuttind down the miner. I've seen many MANY people thinking on the fly means while the miner is running not within windows w/out rebooting.

Keep me posted. I am interested in your status on this.

@luke..... did those settings work for you?
