No1Spank Posted February 2, 2017 Posted February 2, 2017 (edited) I have a single core Sempron for sale that is lapped and had a delid with Gelid GC-Extreme thermal past on the CPU to IHS. I haven't glued it back down as I know some of you prefer liquid metal. Would make a good CPU for a rookie or novice to improve their global single core scores. It's for sale on Ebay for 20 quid with free delivery to anyone in the UK. AMD Sempron 145 Lapped, Delid, & binned 4.2ghz My best scores are with another Sempron 145 which isn't for sale yet.

subaruwrc Posted February 2, 2017 Posted February 2, 2017 put a piece of paper under the actual item and write your name and date on it with price wanted for it to make this a proper for sale thread.
I.nfraR.ed Posted February 2, 2017 Posted February 2, 2017 (edited) Not to spoil the fun, but 4.2ghz at 1.5v is nothing extraordinary. I've sold two low-volt 4.5GHz+ (stock cooling) before and these were my rejects. For hw records they need to have other capabilities, not just pure core clock potential. Any reason to delid it? Aren't they "soldered"? Any thermal paste will be worse than stock and also needs maintenance, i.e. you need to replace the paste regularly. Edited February 2, 2017 by I.nfraR.ed

No1Spank Posted February 2, 2017 Author Posted February 2, 2017 Sorry it's my first post trying to advertise anything for sale, I generally don't sell anything so I'm not that good with ebay either. I thought I was doing well to get a good 4.2ghz on one of these to run any bench in 20 degree C ambient conditions. It wouldn't do that before the delid (they are not soldered), even 4ghz was sketchy. My other one isn't much quicker but has scored me some decent points in the league. Got another one on the way to play with. Deliding older cpu's is definitely worthwhile. I had an E2160 that wouldn't budge over 2.9ghz on air, with a TEC I could bench at 3.2ghz and then after the delid I managed over 3.8ghz on air again and with lower volts. Downside is the glue gets really hard on older processors making it a lot easier to damage the die especially on the socket 775's which is why I've given up on those. AMD processors are fairly easy to do as long as you don't go in very far as there are little resisters around the edges of the die. All Semprons and Athlons have TIM as far as I know but Phenoms and FX's are all soldered. I also did my Haswell i5 4670K, the temps are now a lot lower under load but I didn't manage to squeeze many more mhz.
I.nfraR.ed Posted February 2, 2017 Posted February 2, 2017 Good info, didn't know they have TIM under the IHS. I thought they are soldered just like the Phenoms. Do you have a photo of the naked chip?
No1Spank Posted February 2, 2017 Author Posted February 2, 2017 Whipped the lid off for you, I've only cut the silicone glue off the lid. I can't see that cutting the glue off the die will gain anything, the IHS will still be a bit closer to the cpu and it's the thermal paste that matters.
I.nfraR.ed Posted February 6, 2017 Posted February 6, 2017 Thanks for the picture. This might actually help me hit even higher frequencies with my little 145 in the future. Seems to be a very tight fit, some elements are very close to the IHS edge, just like some s.939 chips. And I think it is advisable to leave the glue on the PCB, otherwise it might lead to excessive pressure on the DIE. You have a free bump
