Upgrade result E6750 to E8500 and I'm not happy

[simba_nl 34]

My Gigabyte P35-DS3 mainboard died yesterday under warranty so I decided to pay a few dimes more to get an upgraded version Gigabyte EP35-DS3P and the dealer offered me a nice discount when I collected also a new CPU so I also bought the E8500.I use FS9 for high and fast and FSX for low and slow

NOOOOO don't say it, my 8500 arrives today. :-( Something must be amiss in your set up somewhere - HD speed not optimal, bad driver install??? Hope you get it figured out but there's no way you should go backwards, to that extent, with your upgrade. You say you swapped out your MB but didn't do a fresh OS install? That usually doesn't work very well from what I've read.

Yeah, I'd definitely delete your FSX.cfg and let it rebuild a new one.Personally, I'd reinstall my OS and FSX after installing a new mobo and CPU. I'm pretty sure you should be seeing gains and NOT losses with the E8500

Yes something is amiss, you should be seeing better frames with the E8500. It will not be earth-shattering though. The E6750 is no slouch. I hope you were not expecting miracles because you had a fast cpu already.I agree with the others, if I had new mb + cpu I would rebuild the OS + fs from scratch. It will pay off in the end, reducing your aggravation level.RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT

simba nlMy Vista cpu index for my E6750 is 5.5. Do we think calculations would be different for my 32 bit system. Not sure how valuable the Windows Experence Index is.Bob

Well, I have my 8500 installed, temps look good but I've noticed that with Intel speedstep enabled, this processor rarely goes up to stock speed of 3.16 GHZ - hangs at 2.0 with a 6 multi and that's running Orthos. This could be happening to you too Simba and would explain you lack of performance. Anyone with ideas on why it won't step up to stock speeds?I'm running auto in the bios for core voltage, which is reading low at 1.12 in cpuz, multi set to 9.5, 333 FSB - other specs in 1st rig below 'cept the cpu.EDIT: Hmm, bumped my cpu warning temp up 10 to 80C and now she steps up - must have been Intel thermal protection? My idle temp in the bios is 26c. Under load is looks like this: Realfan - 48 Speedfan - 68Coretemp - 58 Which is correct? I've heard Realtemp is most accurate with the 45NM's but then why is the thermal protection kicking in at stock speeds?Regards, Kendall#1: E6750@3.2GHZ/Coolermaster HyperTX2 Gigabyte P35-DS3L 4GB Ballistix Tracers PC6400 EVGA 8800GT - 174.74 beta Seagate 250GB 7200.11 CH Yoke/Pedals/Saitek Throttle Dual Monitor: Dell 2405/1905 #2: Dell 8400 3.2 H.T. 3GB PC4200 - X800XT Diamond Xtreme/Logitech X-530's

Therefore, you should disable SpeedStep.If you have a decent BIOS, you should be able to1) disable SpeedStep, and2) manually enter your multiplierI suggest doing both>I'm running auto in the bios for core voltage, which is>reading low at 1.12 in cpuz, multi set to 9.5, 333 FSB ->other specs in 1st rig below 'cept the cpu.>1.12 seems low, the stock voltage for an E8500 is 1.24v. That report may be due to SpeedStep or some thermal protection feature etc., but I am not sure.I suspect that if you disable SpeedStep and manually set multi to 9.5 then you will see it running at 1.24v. If not, if the system is unstable I would be inclined to manually set it at 1.24v.Start by disabling SpeedStep and manually setting your multi. Then see if your temps and voltages are stable. I think that may be the reason you have seen all of this.RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT

Hi Rhett, yep I already had the multi set to max and vcore now ranges between 1.26 and 1.3 and I'm stable @ 3.6 GHZ - I left voltage on auto in preparation to OC, I'll massage it manually when I reach my final destination. My load temps are RealFan 61 , Coretemp 71, speedfan 81. What are your temps and what are you using to monitor them? Everyone says trust Realfan's accuracy, but I wanna make sure.As far as speedstep, I like it enabled as I see no sense keeping the throttle to the boards when I'm not going anywhere. Hope it doesn't hinder my hopes of reaching 4.0. Simba, sorry for crashing your thread with this, did you get it figured out?Regards, Kendall#1: E6750@3.2GHZ/Coolermaster HyperTX2 Gigabyte P35-DS3L 4GB Ballistix Tracers PC6400 EVGA 8800GT - 174.74 beta Seagate 250GB 7200.11 CH Yoke/Pedals/Saitek Throttle Dual Monitor: Dell 2405/1905 #2: Dell 8400 3.2 H.T. 3GB PC4200 - X800XT Diamond Xtreme/Logitech X-530's

Guys, The swapped mainboard is using the same Intel Chipset and the drivers are the same as the old one so a new OS build is not the way I think.I have a dedicated Vista 64 only for FS9 and FSX and also have my normal workarounds on XP under a seperated partition and there is also a performance gain so they both increased.Beside of that, FS9 is running faster/better. The only performance dip is in FSX. I made a fresh build of FSX today but with the same bad result (?!)I have an average Vista performance index of 5.8 and is the cpu on stock speed. The other components have a rating of 5.9 and is the highest visible score in Vista...

>Guys, The swapped mainboard is using the same Intel Chipset>and the drivers are the same as the old one so a new OS build>is not the way I think.>You may be right, no reinstall of OS needed, but in the end analysis it may actually be the right way to do it if all else fails. If I have poor performance in the sim, and I do all of my usual tricks (including driver optimization/cleaning, etc.) and none of it works, then fresh install of the OS is sometimes the only viable solution. Let's hope you don't have to resort to doing that.>Beside of that, FS9 is running faster/better. The only>performance dip is in FSX. I made a fresh build of FSX today>but with the same bad result (?!)>:) well, FS9 is FS9 and FSX is FSX. Even though FS9 is indeed faster after the cpu change, there is no guarantee that FSX will be too. FSX uses the video card and vid driver differently than FS9, too (batching, shaders, etc.). It also uses the cpu a little differently. Those things account for some of the difference.1) Did you also install SP1 and SP2/Accel? Those will make a big difference in the performance of the sim.2) Did you also properly clean and install the vid driver?I ask because you SHOULD see an increase with the E8500 over your older cpu, in FSX. I also migrated to a Vista64 platform with an E8500 (Vista64 Ultimate) and it's quite fast and smooth in the sim, with pretty high settings, too.RhettFS box: E8500 (@ 3.80 ghz), AC Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64ASX Client: AMD 3700+ (@ 2.6 ghz), 7800GT
