buildzoid Posted March 25, 2015 Share Posted March 25, 2015 I managed to fry memory channel B on my 750K by using too high VDIMM(1.85V). I need to know if Kaveri has the same low memory voltage tolerance or will it be OK for about 100 hours at 1.85 VDIMM? Quote Link to comment Share on other sites More sharing options...
The Stilt Posted March 26, 2015 Share Posted March 26, 2015 The maximum official VDDIO for AMD 28nm designs is 100mV less than for 32nm parts. It is highly advised not to exceed 1.7V even temporarily or you will risk frying the IMC. Quote Link to comment Share on other sites More sharing options...
newlife Posted March 26, 2015 Share Posted March 26, 2015 Really? I've run 2.3v on a regular basis on air with richland and 2.4v with cold and no damage done 1 Quote Link to comment Share on other sites More sharing options...

buildzoid Posted March 26, 2015 Author Share Posted March 26, 2015 (edited) Really? I've run 2.3v on a regular basis on air with richland and 2.4v with cold and no damage done I remounted the CPU. Used 2 different motherboards and 2 different kits of RAM in 8 different slot configurations. Channel B is screwed and I never had my NB voltage above 1.375V so channel B died from VDIMM. The maximum official VDDIO for AMD 28nm designs is 100mV less than for 32nm parts.It is highly advised not to exceed 1.7V even temporarily or you will risk frying the IMC. Well that's freaking perfect. I'm using my A88X system as a sort of try stupid stuff test bench which obviously includes high RAM voltage. Now it looks like I need to get a haswell chip to do that.

newlife Posted March 27, 2015 Share Posted March 27, 2015 I am the same person who put 2.2v through a cpu so it's probably best not to listen to a word I say /benchlife This guy knows how much hardware I've killed Quote Link to comment Share on other sites More sharing options...
