![]() Man, this is just ![]() Anyway, my board is still alive and kicking at 2.0V with an uptime of 1 day+ and 6 hours of prime. And I know 2.2V worked as well, didn't actually Prime it for a longer time but say, 30 minutes or so. And before that, it crashed at about 30 seconds. Hope someones gonna come up with a second solution for the vcore problem soon.

Tried setting 2400+ speed at stock 133FSB x15 and 2.1v. Turned system off for twenty minutes to let it cool down. Powered up and siren, no POST. I think the T-Bird 1.4G (before Palamino) still holds the record for using the most power at stock speed. Anybody have one to try in the 8RDA? ET or Holst, In what configuration is the 8RDA+ rated for 2.2v Vcore?

I have some good news to report and a possible fix for this. *Maybe* OK, when I saw you could run the vcore at 2.2 but had to have the CPU at stock speed and not have a shutdown, this showed me it might NOT be an OVP issue. It looked like a heat issue to me. I also read one guy touched his finger to the VRM at 2.2v and he got a giant blister on his finger it was so hot. So in short, I took a 233MM anodized heatsink and cut it up to fit on top of the vcore VRM. The VRM is about the size of a ram chip. But the little heatsink is pretty tall even though it's only six prongs big. I mixed epoxy with thermal paste 50%/50% and glued the sink over the VRM. I let it dry and put a 80mm fan over it. It also blows on the mosfets. As of right now, I'm running Prime since 9:12 and it's 9:42 now at 2.05v and it hasn't shut down yet ![]() Before it would shut down right away. So glue a nice big heatsink on top of the VRM plus a fan. If you don't have an anodized heatsink, just put some tape over the little legs on the VRM so you don't short anything out. Most of the time if you glue it perfectly flat, it won't touch the legs at all. Good luck ![]()

Good job Bondo, I agree that extra cooling is a good idea. Can you try setting Vcore for 2.1v and then see if you can reboot? That would be great if you could all the way to 2.2v. Jeff, Guys like you have all the luck! ![]() Is that your first 8RDA? Any extra cooling on the VR or any mods needed to run Vcore that high?

set it for 2.2 while you're at it.. 2.0 can be done with mod i think

I'll try higher vcore's in a little bit. I want to "break in" the VRM to this vcore before I up it. I don't want to stress it out right away. This whole N2 board needs burning in for it to work right. They should burn the boards in for a day before selling them at 200/200. This is my second "8RMA+" All I did to run like this is what I posted. BUT, I do have water cooling on the NB and the CPU plus the VDD at 1.87v ![]()

lets just see.. ill put a heatsink + fan on the voltage chip... right now i just have a fan... 2.0 was max stable

Prime still running at 2.1v :beer: So guys, you know what job you have to accomplish? Go out there and destroy the enemy. :clown: :clown: Attack that heat! Cut up those heatsinks.... What are you waiting for?????? ![]() ![]() ![]()
