sapphire R9 290 Reference Vs sapphire R9 280x toxic

[rainyman13]

Hey guys
i want upgrade my gpu to one of this cards (only available options for me )

1.sapphire R9 290 Reference
2.sapphire R9 280x toxic

which one is better ? i never overclock my gpu ... so is it ok to go with a Reference crad ro not ?
btw : im gaming on a LG 2286L (1680*1050) display

other spec: M5A97 le r2 .... FX4100 .... 8GB Ram ... CM 600w silent pro

R9 290 is best because of 1GB more VRAM, more VCore and more efficiency. But unfortunately your cpu will bottleneck with your gpu. It will bottleneck with both r9 280x or r9 290. You have to overclock your cpu to reduce bottleneck. Can I give method to overclock?

of course ...How can I do it? ... Sir

Not sir, just bro
I will recommend to do overclocking in bios because it needs less voltage, higher oc and if also increase the processor life comparable to oc by software. Also If you get Any manual settings and of you go for that then the oc will be unstable and will produce more heat. If you give less voltage then you will get unstable oc and if you give higher voltage then it will produce more heat and will reduce CPUs life. So it is important to find a sweet point of correct combination of frequency and voltage. Download the AMD overdrive software to monitor your temps, it will available on official AMD website. To do overclock Just follow this Steps:
1) just enable your XMP memory profile if your memory support that.
2) increase the cpu ratio from factory settings a little(whichever smallest possible) and boot in your os.
3) Download cpu stress testing software prime95 and do a stress test around 20 minutes.
4) if it passes then restart and go in bios, increase a little cpu ratio again a little bit.
5) if it passes then repeat 4th method. And if it not passes then go in bios and increase the CPU voltage and again test. Just keep doing that.
6) a time will arrive when the temp will gone so high, at that time you have to stop and keep it to cool.
7) also when doing upper methods you have to keep a eye on your temps.
8) a step will arrive when prime95 will never pass or the temp will gone so high immediately when stress test started, that point you have to stop and you get the unleashed speed of your processor. You got a stable oc now. Watch temps and don't let them go above 80. Best luck

Remember AMD overdrive gives a thermal margin means temps remain to overheat. It counts temp down not up. Suppose your temp is 50°c and if the thermal margin showing temp 30 ° c then it means that after raise in 30 ° c you cpu will trends to overheat. If the margin is reach to 0°c your cpu is overheated and immediately you have to stop and keep it to cool. That's the way AMD overdrive works.
Don't forget to select the best answer.

thanks a lot bro .... so ... if i overclock my cpu can my power handle both gpu and cpu ?
( for the temp issue i have a CM v10 cpu cooler)

You have to change your PSU to antec, Seasonic, EVGA or xfx. Don't overclock with CM. Which cpu Cooler do you have?

 

[rainyman13]

should i buy a new cpu like fx 6100 - 6300 Instead of a new psu ? ... Cooler master V10 (tec cooler)

No, they will also bottleneck too a little. Also If youget thatyou will to change your mobo to 970 chipset mobo. Even if you get that you will need to overclock it. That also will need a better PSU. Best option to get a PSU. You cpu is good, no need to change it. Just give the budget of your PSU? I will recommend the best.

 

[rainyman13]

thanks ...i already have a 970 chipset mobo so ok then how about this : Antec TruePower Classic TP-650C 80Plus Gold PSU

Antec PSUs are really good and made by Seasonic. Get this. And also it is gold Certified. Beat PSU. You can overclock with it.
And your cooler is best, no doubt. Best design. Now You can overclock your cpu very easily.

Thank you for taking the time to help me
Have a rockin' time \m/

Hope your overclock will be best. Best luck.
