inevitab1e Posted January 8, 2011 Posted January 8, 2011 Hi all, I'm new to overclocking intel chips through the bios and have always had AMD chips. I'm trying to get my RAM to run DDR3-1600 speeds. Mobo: Biostar TH55 HD Memory: Gskill 4G (2x2G) DDR3-1600 9-9-9-24 CPU: i3-540 (133x23) In the bios I can't figure out the settings. This is what I have set for 1600 speeds for the Memory and it doesn't boot. CPU RATIO = 20 BCLK = 160 QPI = Auto DRAM frq = 1600 Timings: tCL=9 tRCD=9 tRP=9 tRAS=24 tWR=10 tWTR=5 tRTP=5 tRFC=40 tFAW=20 CR=2T DRAM read latency = Auto DRAM Write Latency = Auto Intel Speedstep = Disabled C1E Support = Disabled Intel Virtualization = Disabled Voltages: Vcore = Auto VTT = 1.21 PLL = Auto DRAM = 1.645 PCH = 1.10 IGD = Auto I also need to understand the FSB:Ratio's. I'm assuming to go 1:1 I set the DRAM Freq to 1600 for 1:1 (options are AUTO, 960, 1280, 1600) Anyone toss out some opinions? I can run the software OC utility and it puts the CPU around 3500mhz. I think I don't understand the FSB ratio or QPI stuff. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted January 10, 2011 Posted January 10, 2011 (edited) Take cpu vcore off of "Auto" and manually set to 1.275v Manually set VTT to 1.25v Regarding specific settings for the memory timings - manually set the four primary timings (i.e. 9-9-9-24) and put every other memory setting on Auto.

I'm currently hitting high temps of 62c under prime95. I've found a good stable point without pushing up the voltages too much. I believe the VTT is currently at 1.2, would you recommend to increase the volts more or only until there is instability? Doesn't the VTT increase CPU heat and if so, how would you tell if the VTT voltage is too low versus possibly the CPU voltage or RAM voltage being the problem?

wevsspot Posted January 11, 2011 Posted January 11, 2011 (edited) I wouldn't push VTT or any other voltage past the point required for 24/7 stability at the O/C you're aiming to get. If the rig is toaster stable at 1.2v VTT then I'd leave it there. Yes, increasing VTT also increases CPU heat. There isn't any magic formula for figuring out what your VTT should be. It's pretty much all trial and error - although Intel says that anything above 1.35v "may" damage the processor.

While 62c is very hot for a AMD Processor core. Its quite fine for a current gen Intel Processor core... As a generally excepted 24/7 max core temp i think its 72-75c. Of course thats just to give best lifespan. They arent unsafe until they get 100c i believe. It could be slightly different for the 32nm clarkdales. But for the 45nm lynnfield and bloomfield, there isnt anything to worry about until you hit 90c for an extended period of time, or 100c for any reason is pretty bad. So doing some "extreme" benching and hitting 85c for a short period of time really isnt even a problem. Also dont forget, running you ram at anything above 1333mhz is techinically overclocking the internal memory controller. So thats also going to increase the heat of your CPU.

inevitab1e Posted December 24, 2014 Posted December 24, 2014 (edited) Back from the dead with a new situation. Specs are all the same, I tried adding 2x4GB sticks with identical settings as original memory (9-9-9-24 2N) and cannot for the life of me get this system to boot. It's been so long since I messed with overclocking I can't remember what to do or how to problem solve. The system is even acting weird with one stick or the 2 new sticks in the dual channel slots. I bought 2 more sticks of Gskill memory to fill the remaining 2 slots on the board and I get a blue screen immediately after the "Starting Windows" screen. I've reset bios, tried playing with settings and still can't get it to boot. Biostar TH55B HD mobo (LGA 1156) i3-540 2x2GB Gskill DDR3 1600 2x4GB Gskill DDR3 1600 (new) Any help would be appreciated to start. I feel like a rookie after all this time, I'm desperate CPU = http://www.newegg.com/Product/Product.aspx?Item=N82E16819115221 MOBO = http://www.newegg.com/Product/Product.aspx?Item=N82E16813138186 RAM = http://www.newegg.com/Product/Product.aspx?Item=N82E16820231193 New RAM (added to ^) = http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314 New RAM (added to ^) = http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314 Edited December 24, 2014 by tytlyf Share this post Link to post Share on other sites More sharing options...
