E6400 upgrade to e7500 Tags: CPUs Last response: November 8, 2010 10:27 PM in CPUs Share EarpWJ November 6, 2010 9:30:07 PM On the E6400 I am running it at 2.8ghz (8*350) very stable for years. Motherboard is a Asus P5b Deluxe WiFi-AP Does this mean that with the same FSB (350) that I could run the e7500 at the same FSB achieving a 3.85ghz overclock? (350*11=3850)? I assume the only problem I would hit would be CPU heat right? Does this chip run much hotter than a e6400? (The e6400 is going to replace a P4 550 in another comp, so dont tell me just to get a i7 or something ) More about : e6400 upgrade e7500 | E-mail me updates | Report abuse Register or log in to remove rolli59 CPUs Master November 6, 2010 9:46:20 PM Theoretically yes! Not only thermal issues the CPU´s might not run at fsb 350 | Report abuse EarpWJ November 6, 2010 9:58:59 PM I would find that odd if a E6400 FSB is 800 and it can run at my current 1400 (43% over normal) Then it would be less of a stretch for the E6500 (1066FSB) to run at 1400 (only 24% over normal) I have a ZALMAN CNPS9700 any idea if that would be enough? | Report abuse rolli59 CPUs Master November 6, 2010 10:33:34 PM It is a good cooler! CPU´s are not created equal there is always a dud in between, at least your Board is capable which is promising. | Report abuse Related ressources E6400 to E6500 upgrade - Forum DQ965GF Intel board and intel E7500 duo combo - Forum X6800 vs PDC e6300 vs e7500 - Forum E7500 to q9550 worth the $100 upgrade ? - Forum E7500 upgrade ? - Forum Ask the community Publish EarpWJ November 7, 2010 12:14:07 AM Ok, got the E5700, flashed the BIOS (latest beta, but running perfect at current overclock on E6400 so far) and now am going to preform the surgery, wish me luck | Report abuse EarpWJ November 7, 2010 1:34:26 AM I installed the processor and am getting a long continuous high pitch beep, I double checked, its seated properly... I then tried my cold E6400 and get the same long beep. What am I doing wrong? | Report abuse RetiredChief CPUs Authority November 7, 2010 1:45:23 AM You did return everything back to stock before swapping CPUs ????

What is a max temp to watch out for on the motherboard and CPU? | Report abuse rolli59 CPUs Master November 7, 2010 10:01:16 AM E7500 Tcase max 74.1°C = 165.38°F according to Intel http://ark.intel.com/Product.aspx?id=36503 | Report abuse iam2thecrowe CPUs Authority November 7, 2010 7:57:50 PM so you ended up getting the e7500? how is it runing? much faster? | Report abuse EarpWJ November 7, 2010 10:31:05 PM I haven't done any bench marks, but load times are noticeably faster and I think I notice some difference in games with high end graphics. The real big difference is in the E6400 replacing the P4 550 in my wife's gaming comp. Either way I think I went with the right processor, now with the $ I saved on not getting a Q9550 I can now save it for a new video card down the line. Thanks guys. | Report abuse jsc CPUs Master November 8, 2010 12:17:20 PM I got 4.1 GHz (373 MHz X 11) out of my E7500 with a Xig Dark Knight in a Gigabyte EP35-DS3P, 24 hours Prime95 stable. | Report abuse EarpWJ November 8, 2010 10:27:57 PM jsc said:I got 4.1 GHz (373 MHz X 11) out of my E7500 with a Xig Dark Knight in a Gigabyte EP35-DS3P, 24 hours Prime95 stable.
