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 rolli59 a c 850 à CPUs November 6, 2010 9:46:20 PM Theoretically yes! Not only thermal issues the CPU´s might not run at fsb 350 m 0 l 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? m 0 l Related resources Upgrade from E7500 duo to Q9650? - Forum Pentium E2200 vs Core 2 E7500 is it worth the upgrade? - Forum I want to upgrade from my gigabyte E7500 duo to a quad suggestions? - Forum E7500 to q9550 worth the $100 upgrade? - Forum Core 2 E7500 upgrade for dell? - Forum Can't find your answer ?

CPU´s are not created equal there is always a dud in between, at least your Board is capable which is promising. m 0 l 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 m 0 l 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? m 0 l RetiredChief a b à CPUs November 7, 2010 1:45:23 AM You did return everything back to stock before swapping CPUs ???? I also have the E6400 w/Zalman 9500 running @ 3.2 (Bus @ 400), currently my back-up computer. m 0 l iam2thecrowe a c 82 à CPUs November 7, 2010 1:52:24 AM all the power connectors pluged in? hard reset the bios with motherboard jumper? m 0 l EarpWJ November 7, 2010 1:53:08 AM yup, set the BIOS to default still getting the LONG beep on both processors I reseated the ram and video card, no luck... m 0 l EarpWJ November 7, 2010 2:00:15 AM OMFG this always happens to me... thanks... I removed the video card to get easy accses to the cpu, when I reinstalled the video card I forgot to plug in the extra power cable lol.... DUHHHH m 0 l dEAne November 7, 2010 4:57:55 AM I guess your a good computer enthusiast. m 0 l EarpWJ November 7, 2010 9:51:03 AM Running solid at 3.85ghz, highest temp so far was 122f while playing Battlefield Bad Company 2. What is a max temp to watch out for on the motherboard and CPU? m 0 l rolli59 a c 850 à CPUs 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 m 0 l iam2thecrowe a c 82 à CPUs November 7, 2010 7:57:50 PM so you ended up getting the e7500? how is it runing? much faster? m 0 l 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. m 0 l jsc a c 172 à CPUs 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. m 0 l 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.
