pentium D I HAVE A DELL XPS 200 WITH Pentium® D Processor 820 w/Dual Core Technology (2.8GHz,800FSB would i be able to oc the chip if yes how ? thnx in advance
You can overclock any processor, provided the motherboard/BIOS has the necessary options to allow it. The problem with Dell is that they generally use proprietry motherboards and BIOS which are built down to a cost and tend to have very limited extras. I once came a across a PC, not a Dell, but another large supplier and it only had one DIMM slot, with spaces marked out on the motherboard where the other two would normally be, presumably to save the few pence that including them would have cost. Great for profit margins, but not for the customer when they decide to add an extra stick of RAM. In any case, you need to look at the BIOS and see what options are available. Can you alter the FSB and adjust the CPU voltage for starters.
Alright I'll probably order tomorrow, these is the list of the purchase. Anyone has some advice on video card? I heard a lot of artifact issues. Also would this motherboard overclock well? Basically help me out with the list. Please. ASUS P5LD2 Deluxe Socket T (LGA 775) Intel 945P $154.99 XFX PV-T71G-UCF7 Geforce 7900GT 256MB $289.99 Intel Pentium D 805 Smithfield 533MHz $114.49 OCZ Gold (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) $201.99 ZALMAN CNPS9500 AT 2 Ball $62.99 Subtotal: $830.44
805 will be very hot. i recommend a Skythe (sp?) ninja or Tuniq tower for air cooling it. http://www.newegg.com/Product/Product.asp?Item=N82E16835185001 for 35$ that ram is great! im running it on my system, ddr2 1000 stable! thats pc8000! honestly i love my 940. for 170 you can get a 930 dual core, my 940 temps max out at 42 C (water cooled, 4.0ghz). http://www.newegg.com/Product/Product.asp?Item=N82E16819116238 173$ the 7900GT cards that are massively overclocked from the factory are the ones that are messing up. people are putting them in hot systems, then wonder why they cant handle the huge clock speeds. thats what im guessing anyway! get one with a decent (not crazy!) factory oc and get a case with decent cooling. the one you picked seems reasonable, id guess. the deluxe motherboard is sold out, only one is this http://www.newegg.com/Product/Product.asp?Item=N82E16813131538 for 115$ looks like the big difference is two x16 slots, and sata stuff. with those changes its like $815 or so
Ahh too bad PhillyB I've already ordered the components. They're coming tomorrow or the day after. We'll I'll try to do with what I have and see.
the thing to remember, whilst the 805 may overclock up to a high speed, a X2 starts off quite a lot faster, and can also be overclocked. Especially the recent ones. My 939 X2 3800 is up at 2.6 on water, but ran fine at 2.5 on air without boiling (that was with an xp-120 and akasa amber). I'd go with a mildly overclocked 1mb per core x2 over the 805. The cheaper motherboard should make up for the cpu price difference. EDIT: just read that you've ordered already. Have fun with the overclocking You'll get a damn smooth fast pc with that spec.
yep and also one can get a AM2 Sempron and it is cheaper than an 805 and (at least in games) as fast as an 805, and you get an AM2 board you could later upgrade to a double core CPU. Read this anandtech article
What a huge difference, I've got my new parts. It's so much faster, however I did not tweak it yet. Just selected Overclock 30% on Asus BIOS settings =) Although it works great I must say. Will post the results in few days.
Well Oblivion runs at 20-40 FPS with everything at maximum (or nearly, as some things are worthless... like trees hanging in air when you set tree visibility to max) and with HDR on... I'm still to try HDR versus AA. Since this game can only do one or the other. Oh and did I say that when playing Battlefield 2 Demo on everything Fuc#ing high I can only manage to use 80% of CPUs =) This was on 32 man server though. Tried using Vista with my new PC... Hmmm Interesting way Vista calculated your PC rating. 5.2 + 3.6 + 3.8 + 5.9 + 5.8 = 24.3 24.3 / 5 = 4.86 So why again is my rating 3?
Did some benchmarking. (had some problems with memory, will try to fix it) CPU-Z CPU-Z Memory First Everest benchmark: CPU test bench 2 Memory latency test Memory Read Memory write This is weird CPU-Z shows 254MHz memory clock.
This is me first time overclocking so I'm smelling a big mistake I did. Maybe someone could help out a noob? CPU-Z shows 254MHz memory clock but in BIOS: What did I do wrong? BTW if I try to clock higher at 570MHz in BIOS IDE DVD drive and IDE HDD's are recognized, but SATA drives are not. This is pretty weird. Anyone has any thoughts? (and higher memory clocks at same latency results in fail at POST)
If you are referring to the fact that CPU-Z gives a frequency of 253.7, yet the BIOS shows DDR2-507, it's because DDR (Double Data Rate) transfers data at twice the frequency. So when the frequency of RAM is 253.7 MHz, the RAM is actually working at 507 MHz (253.7 x 2 = 507.4).
Flip PCI Clock Synchronisation Mode to "Locked" or "33.33MHz" or similar. The actual setting varies from board to board.
